NOVELTY - Preparing polyaniline nanotube/graphene complex material with tartaric acid as template comprises adding homemade graphene oxide in deionized water, dispersing, adding tartaric acid in a flask containing deionized water, stirring, transferring the flask to the ice water bath, adding aniline and hydrochloric acid solution, stirring in an ice water bath, adding brown graphene oxide dispersion and ammonium sulfate solution, mixing, filtering, washing, adding hydrochloric acid solution, filtering, washing, drying filter cake and collecting. USE - The method is useful for preparing polyaniline nanotube/graphene complex material with tartaric acid as template (claimed). ADVANTAGE - The method: is simple and environmentally friendly. DETAILED DESCRIPTION - Preparing polyaniline nanotube/graphene complex material with tartaric acid as template comprises (a) adding 0.02 g homemade graphene oxide in 50 ml deionized water in a beaker, ultrasonically dispersing for 30 minutes, to obtain brown graphene oxide dispersion, (b) adding tartaric acid in a flask containing 30 ml deionized water, stirring for 0.5 hour, transferring the flask to the ice water bath, adding 0.5 ml aniline and 2 ml hydrochloric acid solution (1 mol/l), stirring for 0.5 hour in an ice water bath, to obtain mixed liquid, where the mass ratio of tartaric acid and aniline is 0.1-5:1, (c) adding brown graphene oxide dispersion with prepared mixed liquid in an ice bath and stirring for 30 minutes, to obtain brown yellow mixed liquid, (d) gradually adding ammonium sulfate solution of brown yellow mixed liquid, mixing for 12 hours, adding 0.6 g tartaric acid to sufficiently reduce graphene oxide mixture, suction filtering deionized water mixture liquid, washing until the filter liquor to neutral, adding 2 ml hydrochloric acid solution (1 mol/l), stirring evenly in an ice water bath, suction filtering product with deionized water, washing until filter liquor is neutral, vacuum drying filter cake at 50 degrees C in an oven for 24 hours, collecting, to obtain polyaniline nanotube/graphene complex material, where the mass ratio of ammonium sulfate and benzene ammine is 1:1
