近些年来,分子刷聚合物的研究受到了广泛关注,这种单分子尺度的聚合物的结构、体积及形状在纳米级别均可以得到精确、灵活的控制,同时,分子刷聚合物的独特结构使其在与不同溶液相互作用时,能够呈现出许多独特的分子形态,为研究溶液与聚合物的相互作用提供了一个理想的平台。本文对环境响应性分子刷聚合物的概念、分类、应用等内容进行了概述,介绍了环境刺激响应性聚合物因其物理化学性质可随外界环境的温度、pH值或离子浓度等因素的变化而变化,这一性能使得它有望在药物输送、催化、制备纳米导线等领域得到广泛的应用。
In recent years, the research of molecular brush polymer has drawn extensive attention. The structure, volume and shape of this single-molecule polymer can be controlled accurately and flexibly at the nanometer scale. Meanwhile, the unique structure of molecular brush polymer It can exhibit many unique molecular morphologies when interacting with different solutions and provides an ideal platform for studying the interaction between solution and polymer. In this paper, the concept, classification and application of environment-responsive molecular brush polymers are summarized. The changes of environmental stimuli-responsive polymers due to their physicochemical properties with temperature, pH value or ionic strength of the external environment The change, this performance makes it is expected to be widely used in drug delivery, catalysis, preparation of nanowires and other fields.
