| Abstract: | A new kind of solid phase change material (PCM) prepared in our laboratory has been studied in this paper. In this PCM, polyethylene glycol (PEG) has been taken as functional branches, with which the energy storage and energy release can be proceeded by phase transition between its crystal state and amorphous state. And chlorinated polypropylene (CPP) has been taken as a skeleton, which ensures the solid nature of PCM during the phase transition. The result shows that the new functional material prepared has great value in use and infinite prospect of development potential. |
