Abstract In order to improve the thermal stability of δ_eform of sPS that possesses nanoporous structure, benzoylation of the phenyl groups was adopted and performed by solution procedure or solid procedure. The solution procedure involves initial benzoylation of sPS in solution and then preparing δ_eform by solvent induction of benzoylated sPS; the solid procedure means benzoylation of δ_eform of sPS in solid state. Usual modifications of sPS by solution procedure greatly decrease the crystallinity of the nanoporous related δ_eform. In this work, sPS can well maintain its crystallinity of δ_eform after benzoylation by solution procedure, even when benzoylation degree reaches 20%. Thermally induced phase transition behaviors of corresponding δ_eform were investigated by Differential scanning calorimeter and temperature-dependent X-ray diffraction analysis. The results show that the δ_e–γ transition temperature increases after benzoylation by both two procedures, indicating improved thermal stability of δ_eform. The subsequent γ–α transition and the melting of α form both shift to lower transition temperature. Meanwhile, the transition of δ_eform to γ form was prohibited by solution procedure contrast to solid procedure.

1.Huahao Yang, Xinyu Cao, Yongmei Ma, Jingjing An, Yucai Ke, Xiaoming Liu, Fosong Wang, Effect of Maleic Anhydride Grafted Polybutadiene on the Compaticility of Polyamide 66/Acrylonitrile-Butadiene-Styrene Copolymer Blend. Polymer Engineering And Science, 2012, 52, 481-488.
Abstract:
The addition of maleic anhydride grafted polybutadiene (PB-g-MAH) can greatly improve the compatibility of polyamide 66 (PA66)/acrylonitrile-butadiene-styrene copolymer (ABS) blends. Unlike the commonly used compatibilizers in polyamide/ABS blends, PB-g-MAH is compatible with the ABS particles' core phase polybutadiene (PB), rather than the shell styrene-acrylonitrile (SAN). The compatibility and interaction of the components in the blends were characterized by Fourier transform-infrared spectra (FTIR), Molau tests, melt flow index (MFI), dynamic mechanical analyses (DMA), and scanning electron microscopic (SEM) observations. The results show that PB-g-MAH can react with the amino end groups in PA66 while entangle with the PB phase in ABS. In this way, the compatibilizer anchors at the interface of PA66/ABS blend. The morphology study of the fracture sections before and after tensile test reveals that the ABS particles were dispersed uniformly in the PA66 matrix and the interfacial adhesion between PA66 and ABS was increased significantly. The mechanical properties of the blends thus were enhanced with the improving of the compatibility.

Abatract:
A shape memory polymer film with a stable micro/nano-fibrous structure is prepared via electrospinning of a triethoxysilane end-capped precursor solution, followed by crosslinking. The fibrous structure is stable and reversible for at least three cycles of shape memory tests. The electrospun SMP film also exhibits consistently faster recovery than the bulk film.

Abstract:
Alumina (Al2O3) fiber/high density polyethylene (HDPE) composites were prepared by molding injection with or without compatibilizer, in which, maleic anhydride-grafted polyethylene (PE-g-MA) and acrylic acid-grafted polyethylene (PE-g-AA) were used as the compatibilizers. The thermal conductivities of the composites were anisotropic and the conductivities in the injection direction of the samples were higher than those in perpendicular direction of the injection. The anisotropic thermal conductivity for Al2O3/PE-g-AA/HDPE was the most obvious and this composite also gave the best mechanical performance. The SEM and DMA test revealed that PE-g-AA was more effective than PE-g-MA in improving the matrix–filler interaction. The high interfacial interaction was more favorable for the viscous flow-induced fiber orientation, which resulted in the largest anisotropic degree of thermal conductivity of the Al2O3/PE-g-AA/HDPE among the studied composite.

1. Jingnan Zhang, Yongmei Ma, Jingjing Zhang, Dan Xu, Qinglin Yang, Jianguo Guan, Xinyu Cao, Lei Jiang, Microfiber SMPU film affords quicker shape recovery than the bulk one. Materials Letters, 2011, 65, 3639-3642.
Abstract:
Comparing to the bulk SMPU (shape memory polyurethane) film, microfiber SMPU film afforded much quicker and sharper shape recovery when heated in water bath. The shape recovery of the microfiber film only took ~ 1/4 time of that needed for the bulk film from Rr (shape recovery ratio) = 10% to Rr = 90%. The final Rr and Rf (shape fix ratio) of the microfiber film was also enhanced. The microfiber film was fabricated by electrospinning with the fiber diameter of 200 nm to 1 μm. DSC and DMA results indicate that the formation of microfiber has very limited effect on the Ttrans (switching temperature) of the SMPU. The quick shape recovery of the microfiber SMPU film is considered due to the higher surface area of microfiber film that is favorable for quicker heating/cooling of the sample and quicker diffusion of water. This study offers a possible way to improve the shape recovery speed without changing the chemical composition, which may meet special needs for sensors or actuators of biomedical devices and others.

Abstract:
The rising commercial use and large-scale production of engineered nanoparticles (NPs) may lead to unintended exposure to humans. The central nervous system (CNS) is a potential susceptible target of the inhaled NPs, but so far the amount of studies on this aspect is limited. Here, we focus on the potential neurological lesion in the brain induced by the intranasally instilled titanium dioxide (TiO2) particles in rutile phase and of various sizes and surface coatings. Female mice were intranasally instilled with four different types of TiO2 particles (i.e. two types of hydrophobic particles in micro- and nano-sized without coating and two types of water-soluble hydrophilic nano-sized particles with silica surface coating) every other day for 30 days. Inductively coupled plasma mass spectrometry (ICP-MS) were used to determine the titanium contents in the sub-brain regions. Then, the pathological examination of brain tissues and measurements of the monoamine neurotransmitter levels in the sub-brain regions were performed. We found significant up-regulation of Ti contents in the cerebral cortex and striatum after intranasal instillation of hydrophilic TiO2 NPs. Moreover, TiO2 NPs exposure, in particular the hydrophilic NPs, caused obvious morphological changes of neurons in the cerebral cortex and significant disturbance of the monoamine neurotransmitter levels in the sub-brain regions studied. Thus, our results indicate that the surface modification of the NPs plays an important role on their effects on the brain. In addition, the difference in neurotoxicity of the two types of hydrophilic NPs may be induced by the shape differences of the materials. The present results suggest that physicochemical properties like size, shape and surface modification of the nanomaterials should be considered when evaluating their neurological effects.
3. Shuai Zhang, Xinyu Cao, Yongmei Ma, Yucai Ke, Jingkun Zhang, Fosong Wang, The effects of particle size and content on the thermal conductivity and mechanical properties of Al(2)O(3)/high density polyethylene (HDPE) composites. Express Polymer Letters, 2011, 5, 581-590.

Abstract:
The influences of filler size and content on the properties (thermal conductivity, impact strength and tensile strength) of Al2O3/high density polyethylene (HDPE) composites are studied. Thermal conductivity and tensile strength of the composites increase with the decrease of particle size. The dependence of impact strength on the particle size is more complicated. The SEM micrographs of the fracture surface show that Al2O3 with small particle size is generally more efficient for the enhancement of the impact strength, while the 100 nm particles prone to aggregation due to their high surface energy deteriorate the impact strength. Composite filled with Al2O3 of 0.5 μm at content of 25 vol% show the best synthetic properties. It is suggested that the addition of nano-Al2O3 to HDPE would lead to good performance once suitably dispersed.
4. Shuai Zhang, Xinyu Cao, Yongmei Ma, Fabrication of alumina ribbons with mixed solvent system in electrospinning. Journal of Optoelectronics and Advanced Materials, 2011, 13, 425-427.
Abstract:
Alumina ribbons were fabricated facilely via using mixed solvent of ethanol and ethyl ether in electrospinning, and α-alumina ribbons were obtained after the as prepared ribbons were calcinated at 1200 oC for 1 h. The as prepared ribbons are composed of dense skin and porous inner structure, the thickness and width of which are of 1 μm and 3-5 μm respectively. After calcination, the corresponding sizes of the ribbons shrunk to ~ 200 nm and 2-3 μm separately. If solo solvent (ethanol) was used in the electrospinning experiment, only round alumina fibers were obtained.

Yi Wei, Yucai Ke, Xinyu Cao, Yongmei Ma, Fosong Wang, Effect of benzoylation on crystallinity and phase transition behavior of nanoporous crystalline form of syndiotactic polystyrene. Polymer, 2013, 54, 958-963.
Abstract In order to improve the thermal stability of δ_eform of sPS that possesses nanoporous structure, benzoylation of the phenyl groups was adopted and performed by solution procedure or solid procedure. The solution procedure involves initial benzoylation of sPS in solution and then preparing δ_eform by solvent induction of benzoylated sPS; the solid procedure means benzoylation of δ_eform of sPS in solid state. Usual modifications of sPS by solution procedure greatly decrease the crystallinity of the nanoporous related δ_eform. In this work, sPS can well maintain its crystallinity of δ_eform after benzoylation by solution procedure, even when benzoylation degree reaches 20%. Thermally induced phase transition behaviors of corresponding δ_eform were investigated by Differential scanning calorimeter and temperature-dependent X-ray diffraction analysis. The results show that the δ_e–γ transition temperature increases after benzoylation by both two procedures, indicating improved thermal stability of δ_eform. The subsequent γ–α transition and the melting of α form both shift to lower transition temperature. Meanwhile, the transition of δ_eform to γ form was prohibited by solution procedure contrast to solid procedure.

Abstract:
The addition of maleic anhydride grafted polybutadiene (PB-g-MAH) can greatly improve the compatibility of polyamide 66 (PA66)/acrylonitrile-butadiene-styrene copolymer (ABS) blends. Unlike the commonly used compatibilizers in polyamide/ABS blends, PB-g-MAH is compatible with the ABS particles' core phase polybutadiene (PB), rather than the shell styrene-acrylonitrile (SAN). The compatibility and interaction of the components in the blends were characterized by Fourier transform-infrared spectra (FTIR), Molau tests, melt flow index (MFI), dynamic mechanical analyses (DMA), and scanning electron microscopic (SEM) observations. The results show that PB-g-MAH can react with the amino end groups in PA66 while entangle with the PB phase in ABS. In this way, the compatibilizer anchors at the interface of PA66/ABS blend. The morphology study of the fracture sections before and after tensile test reveals that the ABS particles were dispersed uniformly in the PA66 matrix and the interfacial adhesion between PA66 and ABS was increased significantly. The mechanical properties of the blends thus were enhanced with the improving of the compatibility.

Abatract:
A shape memory polymer film with a stable micro/nano-fibrous structure is prepared via electrospinning of a triethoxysilane end-capped precursor solution, followed by crosslinking. The fibrous structure is stable and reversible for at least three cycles of shape memory tests. The electrospun SMP film also exhibits consistently faster recovery than the bulk film.

Abstract:
Alumina (Al2O3) fiber/high density polyethylene (HDPE) composites were prepared by molding injection with or without compatibilizer, in which, maleic anhydride-grafted polyethylene (PE-g-MA) and acrylic acid-grafted polyethylene (PE-g-AA) were used as the compatibilizers. The thermal conductivities of the composites were anisotropic and the conductivities in the injection direction of the samples were higher than those in perpendicular direction of the injection. The anisotropic thermal conductivity for Al2O3/PE-g-AA/HDPE was the most obvious and this composite also gave the best mechanical performance. The SEM and DMA test revealed that PE-g-AA was more effective than PE-g-MA in improving the matrix–filler interaction. The high interfacial interaction was more favorable for the viscous flow-induced fiber orientation, which resulted in the largest anisotropic degree of thermal conductivity of the Al2O3/PE-g-AA/HDPE among the studied composite.

1. Jingnan Zhang, Yongmei Ma, Jingjing Zhang, Dan Xu, Qinglin Yang, Jianguo Guan, Xinyu Cao, Lei Jiang, Microfiber SMPU film affords quicker shape recovery than the bulk one. Materials Letters, 2011, 65, 3639-3642.
Abstract:
Comparing to the bulk SMPU (shape memory polyurethane) film, microfiber SMPU film afforded much quicker and sharper shape recovery when heated in water bath. The shape recovery of the microfiber film only took ~ 1/4 time of that needed for the bulk film from Rr (shape recovery ratio) = 10% to Rr = 90%. The final Rr and Rf (shape fix ratio) of the microfiber film was also enhanced. The microfiber film was fabricated by electrospinning with the fiber diameter of 200 nm to 1 μm. DSC and DMA results indicate that the formation of microfiber has very limited effect on the Ttrans (switching temperature) of the SMPU. The quick shape recovery of the microfiber SMPU film is considered due to the higher surface area of microfiber film that is favorable for quicker heating/cooling of the sample and quicker diffusion of water. This study offers a possible way to improve the shape recovery speed without changing the chemical composition, which may meet special needs for sensors or actuators of biomedical devices and others.

Abstract:
The rising commercial use and large-scale production of engineered nanoparticles (NPs) may lead to unintended exposure to humans. The central nervous system (CNS) is a potential susceptible target of the inhaled NPs, but so far the amount of studies on this aspect is limited. Here, we focus on the potential neurological lesion in the brain induced by the intranasally instilled titanium dioxide (TiO2) particles in rutile phase and of various sizes and surface coatings. Female mice were intranasally instilled with four different types of TiO2 particles (i.e. two types of hydrophobic particles in micro- and nano-sized without coating and two types of water-soluble hydrophilic nano-sized particles with silica surface coating) every other day for 30 days. Inductively coupled plasma mass spectrometry (ICP-MS) were used to determine the titanium contents in the sub-brain regions. Then, the pathological examination of brain tissues and measurements of the monoamine neurotransmitter levels in the sub-brain regions were performed. We found significant up-regulation of Ti contents in the cerebral cortex and striatum after intranasal instillation of hydrophilic TiO2 NPs. Moreover, TiO2 NPs exposure, in particular the hydrophilic NPs, caused obvious morphological changes of neurons in the cerebral cortex and significant disturbance of the monoamine neurotransmitter levels in the sub-brain regions studied. Thus, our results indicate that the surface modification of the NPs plays an important role on their effects on the brain. In addition, the difference in neurotoxicity of the two types of hydrophilic NPs may be induced by the shape differences of the materials. The present results suggest that physicochemical properties like size, shape and surface modification of the nanomaterials should be considered when evaluating their neurological effects.

Abstract:
The influences of filler size and content on the properties (thermal conductivity, impact strength and tensile strength) of Al2O3/high density polyethylene (HDPE) composites are studied. Thermal conductivity and tensile strength of the composites increase with the decrease of particle size. The dependence of impact strength on the particle size is more complicated. The SEM micrographs of the fracture surface show that Al2O3 with small particle size is generally more efficient for the enhancement of the impact strength, while the 100 nm particles prone to aggregation due to their high surface energy deteriorate the impact strength. Composite filled with Al2O3 of 0.5 μm at content of 25 vol% show the best synthetic properties. It is suggested that the addition of nano-Al2O3 to HDPE would lead to good performance once suitably dispersed.

Abstract:
Alumina ribbons were fabricated facilely via using mixed solvent of ethanol and ethyl ether in electrospinning, and α-alumina ribbons were obtained after the as prepared ribbons were calcinated at 1200 oC for 1 h. The as prepared ribbons are composed of dense skin and porous inner structure, the thickness and width of which are of 1 μm and 3-5 μm respectively. After calcination, the corresponding sizes of the ribbons shrunk to ~ 200 nm and 2-3 μm separately. If solo solvent (ethanol) was used in the electrospinning experiment, only round alumina fibers were obtained.
