Description

technical field [0001] The invention relates to the technical field of composite graphene materials, in particular to a thermally and electrically conductive graphene composite rubber material and a preparation method thereof. Background technique [0002] Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. For ordinary rubber, it is a good electrical insulator. In order to make the rubber material obtain conductivity and meet the application of rubber in various fields, we usually add conductive fillers to the rubber matrix to give it conductive function. Different from common metal-based and plastic-based conductive composite materials, conductive rubber composite materials exhibit excellent elasticity, stretchability and ...
