Thermally conductive composite films of hexagonal boron nitride and polyimide with affinity-enhanced interfaces

摘要

Thermally conductive ceramic/plastic composite materials are needed in various industries for thermal management. The present work aimed at creating composite films of hexagonal boron nitride (h-BN) particles and polyimide. A thermal conductivity of 7 W m~(-1) K~(-1) was achieved at solids loading of 60 vol% with flexibility maintained.
