摘　　要：微纳米图案赋予了材料表面独特的光学、电学、声学、力学以及生物学等特性,其中具有动态变化形貌的表面图案能够实现对材料表面性能原位实时调控,可用于构建智能表面.能够改变临时拓扑形貌并在外界刺激下恢复初始状态的一类动态表面材料称为图案记忆表面(pattern memorysurface,PMS).PMS在浸润性调节、智能显示、电子器件和信息安全等多个领域具有重要的应用前景,涉及化学、物理、材料和生物多个学科交叉领域,是智能材料研究热点之一.然而,由于基底材料对高分子链在微观尺度上的运动具有束缚作用,如何构筑动态可调的拓扑形貌记忆表面一直是该领域面临的难题.基于此,本专论试图定义高分子材料图案记忆表面特征,并总结PMS有关研究的新进展.重点讨论基于褶皱图案构建PMS的优势,进而介绍了PMS作为智能材料在动态光栅、防伪、反射式显示、细胞培养等领域的应用,同时展望PMS的发展前景.Micro-Nano patterns endow material surfaces with unique optical,electrical,acoustic,mechanical and biological properties.Especially,the patterns with dynamically switchable topography can in situ tune the performance of surfaces on-demand and provide a promising alternative for constructing smart materials.Here,the dynamic patterned surfaces whose morphology are temporarily switchable and can return to their original states after undergoing external stimulation are classified as pattern memory surface(PMS).PMS is of great significance to chemistry,physics,materials and biology,and plays an important role in many advanced applications,such as switchable wetting,smart display,electron devices and information security.However,establishing PMS with dynamically tunable topography is still extensively challenging due to the restricted movement of polymer chains caused by substrate material.In this feature article,we attempt to define the characteristics of PMS and summarize the recent developments of the presented PMS of polymer.The strategies for fabricating PMS based on bilayer wrinkled system are emphatically discussed.In addition to the potential of promoting the next generation of smart materials,PMS holds promise in a wide range of intriguing fields as well,including dynamic grating,anti-counterfeiting,reflective display,and cell culture.
