Problems solved by technology

[0002] At present, with the rapid development of society and economy, all kinds of electronic components are operating at high speed and high power. The use and operation of various electronic equipment will generate more heat. If the heat cannot be dissipated in time , will lead to high temperature and affect the use and life of the equipment, and cause its reliability to decrease
[0003] At present, more and more resin-based materials are used in the fields of outer casings and internal components of daily electrical components, but the thermal conductivity of such materials is extremely low, so it is necessary to solve the thermal conductivity of resin-based materials.
At present, in the existing technologies, the heat conduction function of resin composite materials is realized by adding a large amount of heat conduction fillers, and under the upsurge of graphene research in recent years, it is still unavoidable to add a high content of graphene to enhance Thermal Conductivity of Composite Materials
