The invention provides a three-dimensional capacitor electrode material with graphene surface grafted with polyaniline/titanium dioxide, which is formed by grafting polyaniline and TiO2 nanoparticles on the surface of graphene oxide which is treated by a hydrothermal method and forms a porous space structure with intercommunicated interiors under the induction synergistic effect of Fe2O3 as a template, the particle size of the TiO2 nanoparticles is 10-20nm, the particle size of the TiO2 nanoparticles is 10-20nm, the particle size of the TiO2 nanoparticles is 10-20nm, the particle size of the TiO2 nanoparticles is 10-20nm, and the particle size of the TiO2 nanoparticles is 10-20nm. The polyaniline is in a short fiber shape; the three-dimensional capacitor electrode material does not contain Fe. The capacitance electrode material is high in specific capacitance. 本发明提供了一种石墨烯表面嫁接聚苯胺/二氧化钛的三维电容电极材料，以经过水热法处理在Fe2O3的诱导协同作用下形成多孔隙的内部相互连通的空间结构的氧化石墨烯为模板，表面嫁接聚苯胺和TiO2纳米颗粒形成，其中，TiO2纳米颗粒的粒径为10-20nm，聚苯胺呈短纤维状；所述三维电容电极材料不含Fe。该电容
