英文摘要: In order to satisfy the demand to electrode materials for flexible supercapacitors of low cost and high energy storage,the project will fabricate three-dimensional network composites with a hierarchical controllability and porous distribution characteristics, combining the electrochemical capacitance performance of nanometer inorganic particles and conductive polymers with the microstructural characteristics of the textile fibers, through in-situ methods such as layer-by-layer assembly, sol-gel processing, solvothermal synthesis, electrochemical deposition technique and so on.The preparation conditions, for example, the variety and weaving structure of the textiles, the type and morphology of inorganic particles and complex ways on the structures and morphologies of composite materials will be investigated, and the formation mechanisms of open-space network structures made of fibers, inorganic particles and conductive polymers will be discussed.The composite effects and performance coupling mechanisms produced by electrochemically active substances will be analysized, and the relationships between interface effects due to different compositions, composite modes in the complex systems and ion/electron transportations will be clarified. The electrochemical capacitive behaviors of the electrode materials will be st
