摘要：

In this article, the preparation of microencapsulated hexadecaol with graphene oxide (GO) shell was realized by Pickering emulsion templating. The microencapsulated phase change materials (MePCMs) were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) analysis, differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA). The results showed that the MePCMs with 6 wt% GO had high thermal storage capabilities, excellent shape stability during phase change, and enhanced thermal stability due to the existence of a GO shell protecting the core material from leakage and evaporation. The research provides a novel composite PCM with GO for thermal energy storage.
