▎ 摘　　要

NOVELTY - Highly thermally conductive graphene or titanium composite material preparation involves preparing (S101) oxide graphene colloid, adjusting pH value, and then adding certain amount of electrolyte into oxide graphene colloid. The obtained graphene oxide undergoes electrochemical reduction (S102) to prepare titanium or titanium alloy substrate graphene film. The graphene film is rinsed (S103) and then dried (S104) at a certain temperature for a certain time to give the highly thermally conductive graphene or titanium composite material. USE - Method for preparing highly thermally conductive graphene or titanium composite material (claimed). ADVANTAGE - The method prepares the highly thermally conductive graphene or titanium composite material in a simple, cost-effective and eco-friendly manner with compact and uniform graphene film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flowchart of the highly thermally conductive graphene or titanium composite material preparation method.
