Polymers attached by one end to an interface at relatively high coverage stretch away from the interface to avoid overlapping, forming a polymer "brush." This simple picture may serve as the basis for models in diverse interfacial systems in polymer science, such as polymeric surfactants, stabilized suspensions of colloidal particles, and structures formed by block copolymers. The structure and dynamics of polymer brushes have been the subject of considerable theoretical and experimental activity in recent years. An account is given of recent advances in theoretical understanding of stretched polymers at interfaces, and the diverse experimental probes of systems modeled by brushes are briefly reviewed.
聚合物的一端通过化学键连接到界面上，当聚合物在界面上的覆盖率较高时，聚合物会伸展远离界面以避免重叠，形成聚合物“刷”。这种简单的图像可以作为聚合物科学中不同界面体系模型的基础，例如聚合物表面活性剂、胶体颗粒的稳定悬浮液以及嵌段共聚物形成的结构。近年来，聚合物刷的结构和动力学已经成为相当多理论和实验研究的主题。本文介绍了近年来在理论上对界面上伸展聚合物的理解的进展，并简要回顾了用刷模型模拟的各种系统的实验探测方法。
