▎ 摘　　要

NOVELTY - A graphene/carbon gas gel composite material preparing method involves mixing graphene foam into gel liquid precursor, vacuumizing under 0.1 Pa, for 5-30 minutes to obtain impregnated composite, sealing impregnated composite of graphene foam, sealing in a container, placing in the oven at 50 degrees C for 1-7 days to obtain graphene/gel composite material, and carbonizing under the nitrogen at 600-1000 degrees C for 0.5-12 hours to obtain graphene/carbon gas gel composite material. USE - Method for preparing graphene/carbon gas gel composite material for improving the overall material conductive applications (claimed). ADVANTAGE - The composite material avoids local aggregation and affects the compounding uniformity of the composite material, and can be prepared in simple and easy manner.
