| 摘 要： | 采用接枝共聚法合成了以聚乙二醇（PEG）为相变物质，沸石为骨架的PEG沸石固固相变材料。通过红外光谱（FT-IR）、热失重分析（TGA）和差示扫描量热法（DSC）等测试手段对PEG-沸石固-固相变材料的结构、相变行为及热稳定性进行了研究。结果表明：通过改变PEG的分子量，可以得到不同相变焓和不同相变温度的PEG沸石固-固相变材料，其相变焓可达105.41 J/g，热稳定性良好，起始分解温度高于300 ℃。

| Abstract: | PEG-zeolite solid-solid phase change material was synthesized by graft copolymerization. Polyethylene glycol(PEG) was used for phase change material and zeolite for skeleton. Infrared spectrometry (FT-IR), thermogravimetry analysis(TGA) and differentia scanning calorimetric(DSC) were used to study the microstructure, phase change behavior and thermal stability of PEG-zeolite solid-solid phase change material. Results show that PEG-zeolite solid-solid phase change material has different phase transition enthalpy and phase transition temperature by changing the molecular weight of PEG. The phase change enthalpy is up to 105.41 J/g. The thermostability is so good that the initial decomposition temperature is higher than 300 °C. |
