通过动态力学热分析仪(DMA)和差示扫描热分析仪(DSC)研究了由氯化聚乙烯(CPE)与2,2-甲撑双-(4-乙基-6-叔丁基苯酚)(EBP)和(2-羟基-3-环己基-5甲基)-苯环(ZKF)组成的杂化材料的阻尼性能.对于CPE/EBP杂化材料的DMA分析表明,除了含质量分数为5%的EBP外,CPE/EBP杂化材料呈现了两个明显损耗峰,在CPE基体的玻璃化温度以上出现了一个新的损耗峰.这表明在CPE/EBP杂化材料中,CPE富集相与EBP富集相是共同存在的.然而,CPE/ZKF杂化材料只有一个损耗峰,而且峰的高度随着ZKF含量的增加而明显增加.DSC研究表明,CPE/ZKF杂化材料中的ZKF以无定形态存在.研究结果说明小分子EBP和ZKF在基体材料中的存在形态对构成的杂化材料的阻尼性能产生很大的影响.
