摘要
我们通过时间分辨小角 X 射线散射(SAXS)研究了二氧化硅纳米颗粒(SNPs)自组装成聚合物状结构的动力学。利用动力学模型对 SAXS 数据进行分析后发现,SNP 的自组装过程类似于双功能单体的阶跃生长聚合过程。这项研究为利用各向同性球形纳米粒子构建类聚合物结构提供了一种简便的策略。
Supracolloidal step-growth polymerization of isotropic silica nanoparticles: a time-resolved small-angle X-ray scattering study
We have investigated the self-assembly kinetics of silica nanoparticles (SNPs) into the polymer-like structure by time-resolved small-angle X-ray scattering (SAXS). The analysis of the SAXS data with a kinetic model revealed that the SNPs undergo self-assembly in a process akin to the step-growth polymerization of bifunctional monomers. This study offers a facile strategy to construct polymer-like structures from isotropic spherical nanoparticles.
