摘要: 用光散射技术和透射电镜研究了聚苯乙烯-b-聚甲基丙烯酸氨基丙二醇酯胶束和聚苯乙烯-b-聚丙烯酸胶束在水中的相互作用.结果表明,壳层带有氨基和羟基的聚苯乙烯-b-聚甲基丙烯酸氨基丙二醇酯胶束和壳层带有羧基的聚苯乙烯-b-聚丙烯酸胶束在水中可以通过胶束之间的链交换形成壳层结构致密的杂化胶束,温度的升高有助于胶束之间链交换的进行,并提出了形成杂化胶束的链交换机理.

Abstract: The interaction between the binary micelles self-assembled by polystyrene-block-poly(acrylic acid) (PS-b-PAA) and polystyrene-block-poly(amino propylene-glycol methacrylate) (PS-b-PAPMA) in water was discussed in this paper. The results show the interaction between the binary micelles under a suitable condition results in the formation of a kind of special micelles called half-bred micelles through polymer chain exchanging between PS-b-PAA micelles and PS-b-PAPMA in water. A possible mechanism of chain exchanging is suggested for formation of the half-bred micelles.

Key words: Self-assembly, Half-bred micelles, Chain exchanging, PS-b-PAA, PS-b-PAPMA
