Abstract
To develop stretchable heat transfer materials, thermally conductive natural rubber (TCNR) was newly designed and synthesized by utilizing inherent elastic properties of natural rubber (NR) and introducing thermally conductive monomer (TCM) to NR. Owing to phonon transfer assistance of TCM, TCNR film exhibited around 120% higher thermal conductivity (0.38 W/m∙K) compared to the NR film (0.17 W/m∙K). When the same hexagonal boron nitride (h-BN) content was incorporated, TCNR composites showed higher enhancement in thermal conductivity, and the TCNR composite film fabricated with h-BN of 15 wt% showed the thermal conductivity of 0.87 W/m∙K. Due to the inherent elastic properties of NR, the TCNR composite film fabricated with h-BN of 15 wt% exhibited 140% stretchability. It was demonstrated that the TCNR composites can be utilized as a thermal management material for wearable devices.
