英文摘要： As one of potential electrode materials in flexible supercapacitor, inorganic nanomaterials/conductive polymer composites have drawn much attention. However, due to the uneven dispersion and heterogeneity interface in these composites, their overall performance are limited. In this project, we introduce titanium-oxo clusters as nano building blocks, design and synthesize aniline derivatives which contain clusters. The obtained aniline derivative monomers is further copolymerized with other aniline monomers to prepare a series of aniline conductive polymers containing titanium-oxo clusters (PATCs). Besides, the electrochemical properties and micro-structure of PATCs will be optimized through regulating the synthesis parameters such as tailoring the molecular structure of aniline derivatives and the proportion of monomers. We are going to study the intrinsic links among the electrochemical properties and micro-structure features of PATCs, establish the key controllable synthesis technology of PATCs with excellent electrochemical performance. PATCs are expected to solve the uneven dispersion and significantly decrease interface problems of conventional composites. PATCs, as a kind of novel inorganic-organic conductive polymers, will be promising electrode materials for flexible supercapacitor. This project will pave the way to fabricate flexible supercapacitor electrode materials with excellent integrated performance.
