▎ 摘　　要

NOVELTY - Graphene aluminum-based conductive coating is prepared by coating an aluminum-based substrate with a conductive agent containing graphene and silica sol as components. USE - Graphene aluminum-based conductive coating used for solid capacitor (claimed). ADVANTAGE - The graphene aluminum-based conductive coating has good conductivity, strong adhesion, and good high temperature resistance at 300 degrees C at the same time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene aluminum-based conductive coating, which involves: (A) combining conductive agent, deionized water, dispersant and silica sol under dispersing uniformly to prepare graphene water-based glue; (B) scraping the graphene water-based glue on an aluminum base substrate to form a film; and (C) drying high temperature treatment under protection of inert gas.
