| 摘 要： | 通过自由基本体聚合制备了4-(2-二茂铁基乙烯基)-苯基-七环戊基多面体倍半硅氧烷（POSS1）/聚苯乙烯、 丙烯酰基异丁基POSS（POSS2）/聚苯乙烯以及胺丙基环戊基POSS（POSS3）/聚苯乙烯复合材料。采用XRD和TEM研究了POSS在聚苯乙烯基体中的分散性。结果表明, 部分POSS1以纳米线形态存在于聚苯乙烯基体中, POSS2与苯乙烯共聚以分子级分散于聚苯乙烯基体中, 而POSS3以聚集态晶体存在于聚苯乙烯基体中。热失重分析表明, 3种POSS/聚苯乙烯复合材料的热稳定性均增加, 其中POSS1/聚苯乙烯复合材料的热稳定性最好。与纯聚苯乙烯比较, POSS1/聚苯乙烯和POSS2/聚苯乙烯复合材料的玻璃化转变温度分别提高了约10℃和8℃。

| Abstract: | Three different POSS(4-(2-Ferrocenylethenyl)-phenyl-heptacyclopentyl-POSS(POSS1),acryloisobutyl-POSS(POSS2),aminopropylcyclopentyl-POSS(POSS3)) were respectively added into styrene and POSS/polystyrene composites were prepared by bulk free radical polymerization.The dispersion quality of POSS in the matrix of polystyrene was characterized by XRD and TEM.The results indicate that some POSS1 particles in the POSS1/PS are presented in stripe figure.POSS2 is completely dispersed at molecular level in PS matrix,... |
