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....
The use of graphene aerogel has recently been studied with highly functional phase change materials (PCMs) to create 3D structures for improved thermal conductivity and shape-stabilization. In this study, hybrid graphene aerogels (HGA) comprising graphene oxide (GO) and graphene nanoplatelets (GNP) were prepared. Thermal conductivity was measured and results found thermal conductivity increased linearly with low GNP content and continued to grow at a slower rate with increased GNP. Improvement ...
