NOVELTY - A composite coating contains graphene oxide composite hydroxyl-terminated silicone rubber, ethyl orthosilicate, dibutyltin dilaurate and mixed solvent. The mass ratio of graphene oxide composite hydroxyl-terminated silicone rubber and ethyl orthosilicate is 7:3-9.5:0.5. The content of dibutyltin dilaurate is 0.01-0.1 wt.%. USE - Composite coating (claimed). ADVANTAGE - The composite coating has excellent thermal conductivity and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite coating, which involves dissolving graphene oxide composite hydroxyl-terminated silicone rubber in mixed solvent and stirring under rotational speed of 500-2000 rpm for 0.1-2 hours, then adding ethyl orthosilicate and dibutyltin dilaurate and mixing.
