我们报告了两种生物相容性亲水性均聚物和相应的聚环氧乙烷（PEO）和聚[2-（甲基丙烯酰氧基）乙基磷酸胆碱）（PMPC）的双亲水性二嵌段共聚物的二元混合物的不寻常的水（微）相分离。这些双亲水性嵌段共聚物在浓水溶液中的SAXS分析显示高度水合的纳米结构，并提出了基于这些数据的水合机制。
We report the unusual aqueous (micro) phase separation of binary mixtures of two biocompatible, hydrophilic homopolymers and the corresponding double-hydrophilic diblock copolymers of poly (ethylene oxide) (PEO) and poly[2-(methacryloyloxy) ethyl phosphorylcholine) (PMPC). SAXS analysis of these double hydrophilic block copolymers in concentrated aqueous solution shows highly hydrated nano-structures and a hydration mechanism is proposed based on these data.
