中文摘要: 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.
