NOVELTY - Preparation of ionic liquid modified graphene composite polyaniline hollow microsphere comprises preparing ionic liquid modified reduced graphene oxide by dispersing graphene oxide in water, forming graphene oxide water dispersion, adding ionic liquid catalyst, performing modification reaction to obtain graphene oxide modified by ionic liquid, adding reducing agent, carrying out reduction reaction, filtering, and washing to obtain ionic liquid modified reduced graphene oxide (rGO-IL); preparing oil-in-water Pickering emulsion by dispersing the rGO-IL in water, forming rGO-IL water dispersion liquid as water phase, using organic solvent containing aniline monomer as oil phase, and mixing the two, and using homogenizer to emulsify and obtain oil-in-water type Pickering emulsion; and preparing hollow microsphere by putting the emulsion in ice water bath, gradually adding ammonium persulfate hydrochloric acid solution under the same ice bath, and reacting in ice water bath. USE - The method is for preparation of ionic liquid modified graphene composite polyaniline hollow microsphere. ADVANTAGE - The method is simple and mild.
