研究情况
1. 探索新型磁性功能性材料，增强介电损耗与磁损耗匹配度，拓宽微波吸收频带。
提出通过设计大π键共轭体系的酞氰环结构，为磁性材料提供大量电荷载体的策略，首次采用新型三官能团邻苯二甲腈（TPh）作为有机相与Fe₃O₄进行杂化，成功得到具有高介电响应的新型功能性磁性材料；为进一步提高其微波吸收性能，引入由TPh预聚得到的拥有更多远程分子间电子空穴的介电型酞菁铜有机相，大大提高了Fe₃O₄杂化材料的载流子迁移率，解决了反射损耗频段窄、强度小的问题；为进一步增强介电损耗与磁损耗的匹配度，将含稳定π键共轭体系的特色酞菁铜预聚物与介电性能优异的CNT复合，不仅提高了CNT和Fe₃O₄纳米颗粒之间介电响应和电导率，而且拓展了其有效反射损耗的频带和强度，成为一种极具有潜力的微波吸收剂。
2.设计低阻抗界面、构建丰富表界面效应的分级孔结构锑基电极材料
提出引入RF凝胶稳定相包覆前驱核，利用柯肯达尔效应得到Sb/ZnS@C空心-双壳球结构的策略，其异质结低阻抗界面诱导内建电场，加速了离子/电子的输运速率；扩展到金属有机骨架系列材料，得到MOF衍生的ZnS为核、Sb₂S₃@C为壳的核-双壳正十二面体，为缓冲体积应力变化提供足够的空间，通过协同作用充分发挥各个组分的电化学性能，解决了MOF硫化过程的结构不稳定的问题;开发独特的三维NiSb大孔-薄膜合金材料，得到以泡沫镍为基体的自支撑电极材料，扩大了电解质与电解液的接触面积，缩小离子扩散距离。
3.首次突破磷硫层状纳米结构单一性，构建多孔磷硫球/锑纳米结构
开发新型多孔磷硫球可控结构，提出多孔磷硫球协同单金属Sb复合生长在三维多孔泡沫碳上策略，其超小尺寸和多孔特征缓解电化学过程中的材料粉化与体积膨胀问题，协同提高电荷转移和传输动力学，揭示出优化结构设计能提高电池性能，开启金属-磷硫系列复合物在能源存储领域的崭新应用。
