The present study aims at encapsulating hybrid graphene aerogel (HGA) into 3D graphene foam (GF) to fabricate high-performance composite phase change materials (PCM). Using the chemical vapor deposition (CVD) technique, a 3D hybrid GF/HGA (GH) microstructure was formed to create PW/GH composite PCMs. Thermal conductivity of PW/GH composite PCMs increased due to optimized 3D GH hybrid microstructure....
