▎ 摘　　要

NOVELTY - A graphene/gas-phase white carbon black composite material contains 18-25 pts. wt. graphite oxide powder, 14-20 pts. wt. gas-phase white carbon black, 20-40 pts. wt. ethanol solution, 3-6 pts. wt. polyethyleneimine, 1-5 pts. wt. microcrystalline wax, 3-7 pts. wt. polyimide, 2-6 pts. wt. potassium silicate-sodium silicate, 2-5 pts. wt. nano-titanium dioxide, 4-8 pts. wt. trimethylchlorosilane, 2-8 pts. wt. hexamethyldisilazane, and 2-4 pts. wt. ethylenediamine. USE - Graphene/gas-phase white carbon black composite material is useful for rubber reinforcement and functional filler. ADVANTAGE - The graphene/gas-phase white carbon black composite material has high dielectric constant and excellent mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/gas-phase white carbon black composite material, which involves weighing raw materials, uniformly mixing, heating the mixture and then cooling, ultrasonically dispersing the mixture and then centrifuging, heating the mixture and then drying, and crushing.
