Abstract:

以异丙醇铝(AIP)与正硅酸乙酯(TEOS)为溶胶前驱体、聚乙二醇(PEG)为相变组分,经超声辅助溶胶-凝胶过程制备了SiO2-Al2O3/PEG导热增强型定形相变储能材料。利用FTIR和XRD对SiO2-Al2O3/PEG进行结构表征及结晶性能测定,利用DSC与TGA研究其热性能与热稳定性,利用显微热台与数码拍照技术测试材料的定形效果;利用热导率仪测定了材料的导热系数。结果表明,SiO2-Al2O3/PEG的相变焓值可以达到100J/g以上,低于300℃时具有良好的热稳定性,当SiO2-Al2O3/PEG中的铝硅质量比为0.2:1时,其导热系数可达0.414W/(m·K),导热性能比纯PEG提高39.3%,并具有良好的定形效果。
