Enhancement of the vertical thermal conductivity in conductive silicone composites using hybrid fillers and double-sided coating process

초록

Herein, we propose an effective method for improving the vertical thermal conductivity of conductive silicone composites using thermally conductive hybrid fillers and a double-sided coating process. By applying the resin mixing and screen-printing method instead of the conventional spray coating, it was possible to prevent the shrinkage of the conductive composite fabric. It was found that a higher graphene content in the hybrid filler resulted in a higher thermal conductivity for the conductive composites. Moreover, a double-sided coating of conductive silicone additionally improved the vertical thermal conductivity of the fabric due to the formation of a double-sided heat transfer network.
