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 using a Hot Disk TPS 2500 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.
