▎ 摘　　要

NOVELTY - Preparing graphene/carbon nanotube/polyaniline composite material comprises e.g. (i) oxidizing the graphene oxide to obtain modified graphene oxide, then dispersing the modified graphene oxide in water to obtain a modified graphene oxide suspension and adding concentrated hydrochloric acid, (ii) controlling the temperature of the resultant mixture to below 10 degrees C, adding aniline monomer and dispersing by ultrasonically, carrying out pre-reaction under the condition of the reaction temperature at 0-5 degrees C to obtain aniline-modified grapheme, (iii) maintaining the temperature of the mixture below 5 degrees C, mixing the aniline-modified graphene and carbon nanotubes obtained in resultant step uniformly, adding active manganese dioxide and ammonium persulfate and performing the oxidative polymerization, (iv) separating, washing and drying the reacted materials to obtain hydrochloric acid -doped graphene/carbon nanotube/polyaniline composite materials. USE - The method is useful for preparing graphene/carbon nanotube/polyaniline composite material. ADVANTAGE - The method: is simple, mild and economical; and has excellent electrochemical performance.
