The invention discloses a preparation method of a polyaniline nanowire array/graphene sheet/tin dioxide composite material. A three-dimensional structure of graphene oxide is used as the skeleton, anda polyaniline nanowire array is grown on the surface of the graphene oxide by the electrostatic tension between positively charged nitrogen on an aniline chain segment and an epoxy bond on the surface of the graphene oxide; and positively charged Sn(II) ions enter between negatively charged graphene oxide sheet layers and undergo an oxidation-reduction reaction with the graphene oxide to generateSn(IV) ions, meanwhile the graphene oxide is reduced to graphene, then a sodium hydroxide solution is added, a reaction is performed at 180 DEG C to produce nano-tin dioxide particles deposited between the reduced graphene layers, and a polyaniline nanowire array/graphene sheet/tin dioxide composite material is prepared. The method of the invention is simple, reliable and green, and the preparedcomposite material has a re
