Abstract:
以末端带胺基的聚苯乙烯(PS-NH2)为引发剂,利用N-羧酸内酸酐(N-carbonylanhydride,NCA)法制备一种刚柔二嵌段共聚物聚苯乙烯-b-聚(γ-苄基-L-谷氨酸酯)(polystyrene-b-poly(γ-benzyl-L-glutamate),PS-b-PBLG)杂化聚肽,并研究该聚肽嵌段共聚物的分子结构、热性能、液晶性与自组装形貌的溶剂效应.以氢核磁共振波谱(1H-NMR)和凝胶渗透色谱仪(GPC)表征两嵌段的摩尔比、分子量及其分布.利用示差扫描量热分析仪(DSC)与光学显微镜(POM)考察材料的热性质与液晶性.由小角X射线散射(SAXS)分析得知,两嵌段组分呈交替分布层状结构,聚肽层中α螺旋链在不同溶剂中会发生不同程度折叠;通过透射扫描电镜(TEM)清楚观察到PS-b-PBLG在1,2-二氯乙烷(EDC)中α螺旋折叠形成了条纹式层状形貌,不同于1,1,2,2-四氯乙烷(TCE)中α螺旋完全伸展形成的锯齿式层状形貌.
