摘要
通过差示扫描量热法、热重分析等热分析手段 ,系统分析了用化学法制备的聚乙二醇改性纤维素固态相变材料的热性能 ,并探索了该材料热性能和其结构之间的联系。研究结果表明 ,所制备的固态相变材料具有很好的储能效果和热稳定性。
A new kind of phase change materials was prepared by chemical bonding method.The thermal properties of the materials were investigated systematically by means of DSC and TG.The relationship between the thermal properties and the structures was also studied at the same time.The results show that the solid phase change materials prepared by our laboratory have good energy storage effect and thermal stability.
