The invention discloses a preparation method of a polyaniline/graphene/tin dioxide composite material. Three-dimensional polyaniline/graphene oxide complex colloid is prepared by adopting a hydrothermal method and graphene oxide in the prepared colloid is reduced by utilizing SnCl2; and tin dioxide particles are deposited on the three-dimensional polyaniline/graphene oxide complex by adopting the hydrothermal method, so as to prepare the three-dimensional porous net-shaped polyaniline/graphene/tin dioxide composite material. The method disclosed by the invention has a simple, reliable and green and environment-friendly preparation process, and the prepared polyaniline/graphene/tin dioxide composite material has a regular space structure, good dispersibility, high energy density and power density and an excellent cycling performance, is an ideal super-capacitor electrode material and is particularly suitable for industrial production. 本发明公开了种聚苯胺/石墨烯/二氧化锡复合材料的制备方法。以水热法制备三维聚苯胺/氧化石墨烯复合物胶体，并用SnCl对制备的胶体中的氧化石墨烯进行还原，
