Thermal conductivity model of composite materials and calculation method of thermal conductivity coefficient of composite materials

Composite materials, thermal conductive polymers, and thermal conductive plastics can be divided into:
► Composite thermal conductive plastic
Synthesize polymers with high thermal conductivity, such as those with complete crystals that conduct heat through phonons
► Filled thermal conductive plastic
Fill polymers with high thermal conductivity filler particles, fibers, layers, etc

Filled thermal conductive plastics can be divided into two categories: carbon fiber composite materials for thermal conductivity
► Thermal conductive insulating plastic
Low thermal conductivity, around 1.5W/m · K
The main fillers include metal oxide Al2O3 MgO、SiO2， Metal nitrides such as AlN, Si3N4, BN, SiC, B4C3, etc
► Thermal conductive plastic
The thermal conductivity can reach 5.0W/m · K or higher
The main fillers include metal powder/fiber, graphite, carbon fiber CNT、 Graphene, etc
