Development of effective heat dissipation system has been required as technology advances in electronic devices. To improve the performance of electronic devices, various polymer nanocomposite materials with carbon materials, aluminium oxide, aluminium nitride, and hexagonal boron nitride (h-BN) have been used. Among that, h-BN polymer nanocomposite has attracted increasing attention owing to its unique features such as high thermal conductivity and electrical insulating properties. In this work, we prepared several different type of h-BN polymer nanocomposites. The surface functionalization of h-BN was conducted to enhance interaction with polymer matrix and the efficiency of heat transportation. Characterization of the functionalized h-BN and the composite elastomers was performed using XPS, XRD, TEM, SEM, TGA, tensile testing, and thermal conductivity testing. This work was supported by the NRF grant funded by the Korea government(MSIT), NRF-2019R1G1A1099688. |
