NOVELTY - Preparation of geraniol-graphene oxide sustained-release thermally conductive smoke composite material involves: (S1) adding graphite powder to a pre-oxidation system for pre-oxidation, diluting after reaction is completed, carrying out suction filtration, washing until neutral, and naturally drying to obtain a pre-oxidized graphite powder; (S2) taking concentrated sulfuric acid, putting into an ice bath for cooling, mixing the pre-oxidized graphite powder and sodium nitrate, adding to the concentrated sulfuric acid in the ice bath, slowly adding potassium permanganate, ultrasonically processing, and reacting to obtain a mixed system (A); and (S3) subjecting the mixed system (A) to a water bath reaction under ultrasonic conditions, adding deionized water to stop the reaction after the water bath reaction is completed, then adding hydrogen peroxide, reacting, and adding the hydrochloric acid solution to dissolve to obtain a mixed system (B). USE - The method is useful for preparing geraniol-graphene oxide sustained-release thermally conductive smoke composite material. ADVANTAGE - The method provides geraniol-graphene oxide sustained-release thermally conductive smoke composite material with high thermal conductivity.
