AI Technical Summary
Traditional polycarbonate materials suffer from insufficient thermal conductivity and poor flame retardancy in applications requiring high power and high safety. Furthermore, traditional fillers increase the weight of the material, affecting its mechanical properties and toughness.
Functionalized graphene and multi-walled carbon nanotubes are combined, ultrasonically dispersed and vacuum dried, and then combined with twin-screw extrusion technology to form a highly efficient thermally conductive and flame-retardant composite system. Compatibilizers and flame retardants are added to improve interfacial compatibility and flame-retardant effect.
It significantly improves the thermal conductivity and flame retardancy of the material while maintaining lightweight and good mechanical properties, making it suitable for applications with high safety requirements.
