Four methods of the chemical synthesis of single chiral polyaniline nanofibers, self-assembly, interfacial polymerization method, oligomer-assisted method and secondary doping method were studied and compared. The morphology, structure and optical activity of polyaniline were characterized by Scanning electron microscopy (SEM), Ultraviolet-visible spectroscopy (UV-VIS), Circular dichroism(CD) and X-ray diffraction (XRD). The results showed that the morphology and structure of polyaniline synthesized by the four methods were similar. However, the chiral properties of the PANI were opposite in aqueous solvent and organic solvent systems. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书对审稿人意见逐条回复 -->
