NOVELTY - The preparation of graphene carbon aerogel composite material involves (1) mixing molybdenum dioxide/carbon composite material, glycidyl methacrylate and N-isopropylacrylamide at mass ratio of (10-25):(10-20):(5-10), adding absolute ethanol, ultrasonically reacting for 1-2 hours to make the dispersion uniform to obtain dispersion (A), (2) adding graphene oxide and fluorinated graphene to dimethylformamide at mass ratio of (5-8):(3-5), ultrasonically reacting for 3-5 hours to obtain uniformly dispersed graphene mixture, (3) adding dispersion (A) to the graphene mixture under stirring, and adding polyvinylpyrrolidone, ultrasonically dispersing for 30-60 minutes, adding 1-2 mol/L sodium borohydride solution and reducing under water bath conditions, (4) controlling temperature of the system at 80-110 degrees C for 12-18 hours to obtain hydrogel material and (5) freeze-drying the hydrogel material. USE - Preparation of graphene carbon aerogel composite material. ADVANTAGE - The method enables preparation of graphene carbon aerogel composite material ensuring excellent cycle stability, improved electrochemical performance and enhanced mechanical properties.
