NOVELTY - Graphene aerogel composite material includes 100-140 pts. wt. of graphene, 300-450 pts. wt. of aluminum nanowires, 60-110 pts. wt. of ethylene-vinyl acetate copolymer (EVA), 80-150 pts. wt. polycarbonate (PC), 10-40 pts. wt. silane coupling agent, and 8-30 pts. wt. dispersant. USE - Graphene aerogel composite material. ADVANTAGE - The graphene aerogel composite material has excellent elasticity and mechanical properties is obtained by compounding EVA and PC, and preparation method has simple steps and easy reaction conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene aerogel composite material, which involves: (A) mixing graphene oxide dispersion liquid and the aluminum nanowire dispersion liquid in parts by mass, and heating the mixed liquid to increase the temperature to perform a hydrothermal reaction to reduce the graphene oxide; (B) freeze-drying the graphene-aluminum nanowire mixture at (-70)-(-55) degrees C for 12-36 hours to obtain a graphene-aluminum nanowire aerogel; (C) mixing the EVA solution, dispersant and silane coupling agent solution in parts by mass to obtain an elastic mixed liquid, and filling the elastic mixed liquid into the graphene-aluminum nanowire aerogel by vacuum dipping, then taking out and drying under ventilation to obtain graphene-aluminum nanowire EVA elastic aerogel; and (D) mixing the PC solution and the dispersant in proportion to obtain the strength mixture, and filling the strength mixture into the elastic aerogel by vacuum immersion, and taking out and drying under ventilation conditions to obtain the graphene aerogel composite material.
