Problems solved by technology

[0002] Polypropylene has good mechanical properties and thermal stability, but also has good electrical properties, heat resistance and corrosion resistance, and is widely used in electronic communications, lighting fixtures, automobiles, electric tools, electrical switches and other fields. But its relatively Low thermal conductivity (0.21~0.26w / mk) limits its application range in lighting and communication heat conduction and heat dissipation
[0003] At present, domestic research on thermally conductive composite materials is mainly based on filling thermally conductive fillers such as aluminum nitride, magnesium oxide, aluminum nitride, graphite, and carbon powder. However, the amount of such thermally conductive fillers is large, which makes the mechanical properties of the composite materials not good. Good, low thermal conductivity
