NaI-catalyzed reversible complexation mediated living radical polymerization (RCMP) was combined with polymerization induced self-assembly (PISA) to generate self-assemblies. Poly(methacrylic acid) (PMAA) and poly(methyl methacrylate) (PMMA) were used as hydrophilic and hydrophobic segments, respectively, to generate self-assemblies. Micelles (nano-particles), worms (nano-cylinders), and vesicles (nano-capsules) were generated in ethanol at 5–9 wt% solid content. The self-assemblies were also fixed (crosslinked) by using a cross-linkable divinyl monomer, i.e., ethylene glycol dimethacrylate (EGDMA), as a co-monomer in the hydrophobic segment. NaI-catalyzed RCMP is a heavy-metal-free and sulfur-free synthetic method. The nano-particles, cylinders, and capsules obtained through the RCMP/PISA process are highly attractive for biomedical, healthcare, cosmetics, and agrochemical release applications.

通过可逆络合介导的聚合（RCMP）和聚合诱导的自组装（PISA） 合成无过渡金属和无硫的纳米颗粒和纳米胶囊†

NaI催化的可逆络合介导的活性自由基聚合（RCMP）与聚合诱导的自组装（PISA）结合生成自组装。聚甲基丙烯酸（PMAA）和聚甲基丙烯酸甲酯（PMMA）分别用作亲水链段和疏水链段，以产生自组装体。胶束（纳米颗粒），蠕虫（纳米圆柱）和囊泡（纳米胶囊）在乙醇中的固含量为5-9 wt％。通过使用可交联的二乙烯基单体，也可以固定（交联）自组装体，即乙二醇二甲基丙烯酸酯（EGDMA）作为疏水链段中的共聚单体。NaI催化的RCMP是一种不含重金属和不含硫的合成方法。通过RCMP / PISA工艺获得的纳米颗粒，圆柱体和胶囊对生物医学，医疗保健，化妆品和农用化学品释放应用具有很高的吸引力。
