▎ 摘　　要

NOVELTY - A doped composite graphene oxide composite coating comprises main agent, crosslinking agent, mixed solvent, and catalyst. The solid content of the composite coating is 30-70 wt.%. The main agent is graphene oxide composite terminal hydroxyl polydimethylsiloxane. The crosslinking agent is ethyl orthosilicate. The catalyst is dibutyltin dilaurate. The mass ratio of main agent and crosslinking agent is 7:3-9.5:0.5. The content of catalyst is 0.01-0.1 wt.%. USE - Doped composite graphene oxide composite coating. ADVANTAGE - The coating has good heat conductivity and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite coating comprising dissolving graphene oxide composite terminal hydroxyl polydimethylsiloxane in mixed solvent and stirring at 500-2000 revolutions/minute for 0.1-2 hours; and slowly adding ethyl orthosilicate and catalyst dibutyltin laurate, and solidifying and forming at room temperature.
