两亲性嵌段聚合物的同步辐射小角x射线散射研究

Analysis of the aggregation structure from amphiphilic block copolymers in solutions by small-angle x-ray scattering

应用同步辐射小角x射线散射 (SAXS)方法研究了不同聚合条件下苯乙烯 对乙烯基苯甲酸两亲性嵌段聚合物的聚集行为 ,结果发现该聚合物在选择性溶液中自组装形成胶束 .胶束的形态和结构取决于嵌段聚合物的组成。

<Abstract > The aggregation structure of polystyrenep vinyl benzonic amphiphilic block copolymers which were prepared in different conditions was investigated by synchrotron radiation smallangle xray scattering(SAXS). The micelle was selfassembled in selective solvents of the block copolymers. Our results demonstrate that the structure of the micelle depends on the factors, such as the composition of the copolymers, the nature of the solvent and the concentration of the solution.
