刺激响应性核壳微凝胶粒子的合成、表征及应用研究进展

Recent advances in stimuli-responsive core-shell microgel particles: synthesis, characterisation, and applications

Julian Oberdisse, Thomas Hellweg

摘要:

受Matthias Ballauff在过去20年中所遵循的路径的启发,综述了温敏核壳微凝胶结构的发展。不同的化学方法,从硬纳米颗粒核心到双重刺激响应微凝胶,已经被许多不同的小组设计并成功实施。一些丰富的各种各样的这些系统,以及一些最近的进展,这种微结构的中子或X射线的小角度散射,包括建模方法的结构分析。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-稳定纳米颗粒并给予外部控制活性-以及界面处的核壳微凝胶。

英文摘要:

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 approaches, 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 modeling 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 -- stabilizing the nanoparticles and granting external control over activity -- will be discussed, as well as core-shell microgels at interfaces.
