Problems solved by technology

However, some application components are installed near the heat source or light source or directly in contact with the heat source or light source. During the working process, the heat source or light source will generate a lot of heat. These components are required to have good heat dissipation performance, but the thermal conductivity of thermoplastic polymer materials is very small, about 0.04-0.5W / (m K) (1 / 600-1 / 500 of metal), and the heat dissipation efficiency is very low , therefore, expanding the application of thermoplastic polymer materials in the field of heat dissipation and improving the thermal conductivity of materials has become a key issue
