假设固定囊泡结构的一种有效方法是将单体和交联剂插入囊泡的双层中，随后的聚合可以导致聚合物纳米囊泡的形成。这里特别有吸引力的是囊泡系统，形成自发的良好定义的小囊泡，因为获得这样的小nanocaptiles与尺寸低于100 nm的仍然是challenging.ExperimentsA自发形成的良好定义的囊泡系统组成的表面活性剂TDMAO（氧化十四烷基二甲基胺），普朗尼克L35，和LiPFOS（全氟辛基磺酸锂）的混合物被用作模板，通过聚合固定。因此，苯乙烯单体被纳入囊泡双层，并最终通过UV诱导的自由基聚合固定这些结构。通过浊度测量、动态和静态光散射，（DLS，SLS）和小角中子散射（SANS）。并且这些结构可以通过聚合过程变得永久固定。这种方法产生良好定义的纳米胶囊从自组装系统和以下聚合的潜力进行了严格的评估。
HypothesisAn effective way for fixating vesicle structures is the insertion of monomers and cross-linking agents into their bilayer, and their subsequent polymerization can lead to the formation of polymeric nanocapsules. Particularly attractive here are vesicle systems that form spontaneously well-defined small vesicles, as obtaining such small nanocapsules with sizes below 100 nm is still challenging.ExperimentsA spontaneously forming well-defined vesicle system composed of the surfactants TDMAO (tetradecyldimethylamine oxide), Pluronic L35, and LiPFOS (lithium perfluorooctylsulfonate) mixture was used as template for fixation by polymerization. Therefore, styrene monomer was incorporated into the vesicle bilayer and ultimately these structures were fixated by UV induced radical polymerization. Structural alteration of the vesicles upon loading with monomer and the cross-linker as well as the effect of subsequent polymerization in the membrane were investigated in detail by turbidity measurements, dynamic and static light scattering, (DLS, SLS), and small angle neutron scattering (SANS).FindingsThe analysis showed the changes on vesicle structures due to the monomer loading, and that these structures can become permanently fixed by the polymerization process. The potential of this approach to produce well-defined nanocapsules starting from a self-assembled system and following polymerization is critically evaluated.
