A novel hyperbranched polyurethane solid-solid phase change heat storage material (HB-PUPCM) using hyperbranched polyester as chain extender was synthesized via a two-step process. Differential scanning calorimetry (DSC) and polarizing optical microscopy (POM) were performed to investigate the phase transition behaviors and crystalline morphology. The results indicated that the HB-PUPCM was a good polymeric solid-solid phase change heat storage material.
