Graphene oxide was reduced and functionalized with long chain alkylamine, oleylamine (OA), to adsorb palmitic acid (PA) and was simultaneously self-assembled into a three-dimensional structure. This technique eliminates common freeze-drying and impregnation steps since the phase change material is adsorbed in situ, and there was clearly no shrinkage during the drying process. In addition, the connected graphene network provides nuclei for the heterogeneous nucleation and crystallization of PA with an enhanced heat transfer to and from the PCM and retains excellent shape-stable property which prevents the leakage of molten PA. The obtained composites exhibit a large phase change enthalpy (99.6%), enhanced thermal conductivity (150%), excellent cycling performance, and substantial sunlight adsorption. � 2015 American Chemical Society.
