NOVELTY - Preparation of tungsten trioxide/polyaniline/graphene composite material involves dissolving phosphotungstic acid ethanol, and drying to get tungsten trioxide; ultrasonically dispersing tungsten trioxide in hydrochloric acid solution, adding aniline monomer, adding hydrochloric acid solution and ammonium sulfate, shaking, , centrifuging, washing and freeze-drying to get tungsten trioxide/polyaniline; and dispersing tungsten trioxide/polyaniline in graphene oxide, adding hydrochloric acid, adding zinc powder, sonicating, adding hydrochloric acid, centrifuging, washing, and freeze-drying. USE - Method for preparing tungsten trioxide/polyaniline/graphene composite material (claimed). DETAILED DESCRIPTION - Preparation of tungsten trioxide/polyaniline/graphene composite material comprises preparing tungsten trioxide by weighing phosphotungstic acid, dissolving in ethanol, and drying completely at room temperature for 4 hours; preparing tungsten trioxide/polyaniline by ultrasonically dispersing 0.2 g tungsten trioxide in 10 mL to 1 mol/L hydrochloric acid solution, adding aniline monomer, adding 10 mL 1 mol/L hydrochloric acid solution and ammonium sulfate, quickly shaking at room temperature for 30 seconds, standing for 4 hours, centrifuging, washing, freezing and drying; and dispersing 0.2 g tungsten trioxide/polyaniline in 10 mL 1 mg/mL graphene oxide, adding 0.9 mL concentrated hydrochloric acid, adding zinc powder, sonicating for 30 minutes, adding 1 mL concentrated hydrochloric acid to remove excess zinc powder, centrifuging, washing, freezing and drying.
