▎ 摘　　要

NOVELTY - A high conductivity polymer composite material comprises a uniformly distributed three-dimensional interconnected network of graphene (5-20 wt.%). USE - A three-dimensional graphene network high conductivity polymer composite material for electromagnetic shielding, conductive adhesive, a sensor, or a brake. ADVANTAGE - The composite material has reduced contact resistance between them, high conductivity, and simple and easy to control preparation method that can be applied to a large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing a high conductivity polymer composite material comprising mixing (g/ml) graphene oxide (0.2-2) and cationic polymer latex particles (1-5), adjusting pH value to 2-5, adding mixture to a solvent, filtering, condensing in the presence of a weak acid to form a film, adding a reducing agent to oxidized graphite alkene at 50-90 degrees C, washing, vacuum drying, and pressing.
