NOVELTY - Preparation of thermal conductive gasket involves dipping, spraying or casting a graphene dispersion to a template, drying to obtain a template structure of graphene composite, removing the template from the template structure to obtain a three-dimensional film-like graphene network structure, filling the three-dimensional film-like graphene network structure with silica gel containing insulating and thermal conductive filler to obtain a thermal conductive gasket sample, and encapsulating an encapsulation layer on the sample. USE - Preparation of thermal conductive gasket (claimed). ADVANTAGE - The process effectively eliminates the defects of ordered arrangement of graphene to achieve the requirements of high thermal conductivity, and defects of insulation to achieve the test requirements of breakdown voltage.
