Graphene woven fabric-reinforced polyimide films with enhanced and anisotropic thermal conductivity

The in-plane thermal conductivity of polyimide composite films with 12 wt% graphene woven fabrics content achieves 3.73 W/mK, whereas the out-of-plane thermal conductivity of the composites is only 0.41 W/mK, indicating a highly anisotropic thermal conduction.239
