Inspired by the path followed by Matthias Ballauff over the past 20 years, the development of thermosensitive core-shell microgel structures is reviewed. Different chemical structures, from hard nanoparticle cores to double stimuli-responsive microgels have been devised and successfully implemented by many different groups. Some of the rich variety of these systems is presented, as well as some recent progress in structural analysis of such microstructures by small-angle scattering of neutrons or X-rays, including modelling approaches. In the last part, again following early work by the group of Matthias Ballauff, applications with particular emphasis on incorporation of catalytic nanoparticles inside core-shell structures—stabilising the nanoparticles and granting external control over activity—will be discussed, as well as core-shell microgels at interfaces.

刺激响应核壳微凝胶颗粒的最新进展：合成、表征和应用

受马蒂亚斯·巴拉夫 (Matthias Ballauff) 过去 20 年所走路径的启发，回顾了热敏核壳微凝胶结构的发展。许多不同的团体已经设计并成功实施了不同的化学结构，从硬纳米粒子核心到双重刺激响应微凝胶。介绍了这些系统的一些丰富多样性，以及通过中子或 X 射线的小角度散射对此类微结构进行结构分析的一些最新进展，包括建模方法。在最后一部分中，再次遵循 Matthias Ballauff 小组的早期工作，将讨论特别强调将催化纳米颗粒掺入核壳结构中的应用——稳定纳米颗粒并授予对活性的外部控制—— 以及界面处的核壳微凝胶。图形概要
