摘要
环境响应型聚合物是近年来受到广泛关注的功能材料,这种类型的共聚物可以对外部环境刺激而产生相应的结构,物理和化学变化。根据外部环境刺激反应的机理和类型的不同,分为单刺激响应与多重刺激响应。本文重点讨论关于环境响应型共聚物的设计,合成,自组装和应用的研究现状,总结说明了当受到pH,温度,光照,CO_(2),氧化还原剂等外部环境刺激时各类有序聚集体所表现的变化,展望了智能嵌段共聚物在药物控释,纳米容器制备和生物功能材料中的潜在应用价值和未来的发展方向。
Environmentally responsive polymers are functional materials that have received extensive attention in recent years.This type of copolymer can stimulate the external environment and produce corresponding structural,physical changes and chemical changes.According to the different mechanisms and types of external environmental stimuli,divided into single stimulus response and multiple stimulus response.This article focuses on the research status of design,synthesis,self-assembly and application of environmentally responsive copolymers.The summary explains the changes in various ordered aggregates when exposed to external environmental stimuli such as p H,temperature,light,CO_(2),redox agents,etc.Introduce the potential application value and future development direction of smart block copolymers in controlled drug release,nano-container preparation and biological functional materials.
