摘要
通过利用差示扫描量热法(DSC)对不同分子量的聚乙二醇(PEG)进行了相变过程中热力学参数的测定,得出聚乙二醇的贮热能力在一定聚合度范围内随聚合度的增加而增强的规律。
Thermodynamic parameters of different molecular weight polyethylene glycol (PEG) in the phase change process were measured by using DSC. The results show that capability of PEG thermal energy storage is enhanced with increasing of polymerization degree in the range of certain polymerization degree.
