摘要

我们通过实验和分子动力学模拟，研究了具有多室化结构的聚合物/无机杂化胶体粒子的形成，这种粒子由接枝了聚苯乙烯-嵌段-聚甲基丙烯酸（PSt-block-PMAA）二嵌段共聚物配体的金纳米粒子组成。PMAA 嵌段分离成类似卫星的小域，这些小域被聚苯乙烯间隔物与金纳米粒子核心隔开。通过对水的透析，形成的结构被重新配置为独特的、具有内部结构的动力学捕获针状微粒装饰纳米粒子。

Multicompartmentalized Micellar Structures by Gold Nanoparticles Grafted with Diblock-Copolymer Ligands.

We study the formation of hybrid polymer/inorganic colloidal particles with multicompartmentalized structure, comprising gold nanoparticles grafted with polystyrene-block-poly(methacrylic acid) (PSt-block-PMAA) diblock copolymer ligands, through experiments and molecular dynamics simulations. The PMAA blocks segregate into small satellite-like domains that are separated by the polystyrene spacer from the gold nanoparticle core. Dialysis against water leads to the re-configuration of the formed structures into unique, kinetically trapped pinned-micelle-decorated nanoparticles with internal structure.
