- 摘要:
- 环氧乙烷链具有低临界溶解温度(LCST)效应,其在水溶液中会随着温度变化在水合作用-脱水作用之间进行可逆的转化,从而引发分子构象的变化,并最终改变分子聚集体的形貌和性质.本文将介绍基于聚环氧乙烷链为柔性链段的刚柔嵌段小分子在水溶液中形成的多种热响应纳米结构以及它们的自组装行为原理,为热响应纳米材料的制备和研究提供参考.
- Abstract:
- Among the LCST systems, flexible poly(ethylene glycol)(PEG)chains can be dehydrated reversibly with the change of temperature, which makes PEG as a good soft segment of flexible-rigid block molecules for the preparation of thermal-responsive supramolecular nanostructures. In this mini review, diverse thermal-responsive nanostructures, based on the poly(ethylene glycol)(PEG)chains, from self-assembly of rigid-flexible block molecules in aqueous solution will be described.
