In this work, polyurethane (PU)/paraffin wax (PW) nanoencapsulated phase change material (NEPCM) for thermal energy storage was synthesized by interfacial polymerization method. The microstructure, thermal properties and thermal performance of NEPCM were characterized by transmission electron microscopy (TEM), differential scanning calorimetry (DSC) and temperature-time curve, respectively. The results showed that the interfacial polymerization technique can be successfully applied for the synthesis of PU/PW NEPCM with good encapsulation efficiency (44.3 %), a high latent heat capacity (67.3 ℃, 82.8 J/g), and good thermal performance, which indicates that it has a good thermal energy storage with phase change from solid to liquid phase.
