▎ 摘　　要

In this paper, three-dimensional graphene network encapsulating 1-hexadecanol composite was prepared by one-pot method, which is based on Pickering emulsion template. The composite phase change materials (PCMs) showed enhanced thermal conductivity and electrical conductivity due to the interconnected graphene network in PCMs. In addition, the composite PCMs exhibited excellent shape stability, which prevented the leakage of PCMs during phase change. This novel shape-stable PCM can be used in thermal energy storage and conversion. (C) 2016 Elsevier Ltd. All rights reserved.
