Abstract: 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 of thermal conductivity efficiency can be characterized by thermal conductivity enhancement per mass fraction of filler.
