We have developed a thermally conductive flexible elastomer as a composite materials with slide-ring (SR) materials and boron nitride (BN) particles surface-modified via plasma in solution. This seems to be a promising materials as a flexible insulator for thermal management. Fourier transform infrared spectrum, Raman spectrum, and X-ray diffraction patterns of BN particles indicate that plasma-surface modification introduces OH functional groups on surface of BN particles. Furthermore, X-ray computed tomography of the composite indicates the plasma-surface modification dramatically improves BN dispersibility in SR.
