本发明公开了种碳量子点-聚苯胺/碳纤维体化复合材料及其制备方法和电化学储能应用。本发明将可聚合的苯胺单体与导电碳量子点共同作用体化反应形成碳量子点与聚苯胺体化复合材料。碳量子点-聚苯胺纳米线复合材料直接生长于碳纤维导电基底的表面，彼此相互连接形成3D网格式结构，碳量子点均匀地分布于聚苯胺纳米线阵列的内层与表面，碳量子点-聚苯胺/碳纤维体化复合材料可直接作为无粘合剂的超级电容器电极材料，实现电化学储能。碳量子点的存在，不仅提高了聚苯胺纳米阵列材料的电导率，同时为聚苯胺分子提供了有利的支撑，加固了聚苯胺的机械强度，减缓了其主链在长期循环中的破坏程度，增强聚苯胺电极材料的循环寿命。 The invention discloses a carbon quantum dots-polyaniline/carbon fiber integrated composite material, its preparation method and application. According to the invention, the polymerizable aniline monomer acts together with the conductive carbon quantum dots under an integrated reaction to form a carbon quantum dots-polyaniline integrated composite material. The carbon quantum dots-polyaniline nano-wire composite materials are directly grown on the surface of a carbon fiber's conductive substrate and are connected to each other to form a 3D mesh structure. The carbon quantum dots are evenly distributed in the inner surface of the polyaniline nanometer array, and the carbon quantum dots-polyaniline/carbon fiber integrated co
