Heat dissipation is getting tremendous attention due to the rapid evolution of electronic devices toward high power densities, and miniaturization. Most of the polymer-based composites usually present limited the enhancement of thermal conductivity due to high phonon scattering. The addition of highly thermal conductive materials, such as Al2O3, AlN, BN, etc., is an effective strategy to enhance the thermal conductivity of polymers. In this research, we prepared several type of boron nitride (BN)/polymer nanocomposites. The functional groups grafted to the surface of BN was conducted to enhance interaction between the BN and polymer matrix and the efficiency of heat transportation. The thermal properties of the BN/polymer composites were confirmed using an IR thermal imaging spectrometer, DSC, and LFA 457.
