摘    要:以N-异丙基丙烯酰胺(N-isopropylacrylamide)和甲基丙烯酸甲酯基笼状低聚倍半硅氧烷(MAPOSS)为原料,通过自由基聚合制备了P(NIPAM-co-MAPOSS)共聚物。用傅里叶红外光谱(FTIR)、核磁共振(1H NMR)对共聚物的结构进行了表征。用差示扫描量热仪(DSC)研究了P(NIPAM-co-MAPOSS)共聚物水溶液的温敏性能,少量POSS的加入降低了PNIPAM的最低临界转变温度,考察了不同POSS含量的P(NIPAM-co-MAPOSS)共聚物的表面润湿性能,水接触角随着POSS含量的增加而增大。

关 键 词:多面体低聚倍半硅氧烷  N-异丙基丙烯酰胺  温敏  润湿性

Abstract:P(NIPAM-co-MAPOSS) copolymers were synthesized via in situ copolymerization of N-isopropylacrylamide(NIPAM) and Methyl Methacrylate Polyhedral Oligomeric Silsesquioxane(MAPOSS).The structure of copolymer were characterized by FTIR and 1H NMR.The thermo-sensitive properties of the P(NIPAM-co-MAPOSS) copolymer aqueous solution were studied by DSC.Lower Critical Solution Temperature(LCST) decreased when increasing the POSS content.The surface wetting properties of P(NIPAM-co-MAPOSS) copolymers with different POSS content were explored,which showed that water contact angle increased with raising POSS content.
Keywords:Polyhedral Oligomeric Silsesquioxane  N-isopropylacrylamide  thermo-sensitive  contact angle
