This study aimed at developing polymer-based dielectric materials with high charge-discharge efficiency and large energy density at high temperatures. A polymer nanocomposite was formed using c-BCB polymer matrix with two-dimensional hexagonal boron nitride nanosheets (BNNS). Using a transient technique, thermal conductivity was measured with a Thermal Analyzer. The incorporation of BNNS into PMMA was found to increase thermal conductivity and enhance properties of the nanocomposites....
In this study, effective thermal conductivity of nanocomposites containing thermally conductive aluminum nitride (AIN) nanoparticles reinforced with high-density polyethylene (HDPE) was investigated. Measurements were performed using a Thermal Constant Analyzer. The authors found that effective thermal conductivity of HDPE/AIN composites with 20 vol.% of AIN nanoparticles shows an enhancement by about 40%, compared to pure HDPE at 30°C....
