Abstract
A method for preparing a graphene thermal conductive pad is referred. Graphene foam sheets are used as base materials for the graphene thermal conductive pad. The graphene foam sheets are processed by surface crust removal, laser perforation and edge trimming, plasma activation, and multiple modification treatments to yield the graphene thermal conductive pad. The plasma activation causes the hydroxyl functional groups to be generated on the graphene surface. By using hydroxyvinyl silicone oil diluted with xylene, a small amount of hydroxyvinyl silicone oil uniformly covers the graphene surface. Heating induces dehydration condensation between the hydroxyvinyl silicone oil and the hydroxyl groups generated by plasma activation, forming chemical bonds. In such a way, a tighter interface between the graphene and the subsequent adhesive is achieved, pores at the interface are reduced, thereby lowering thermal contact resistance, improving heat transfer efficiency, and enhancing tensile strength and compression resilience.
