摘　　要：聚合物材料表面微结构对其功能化的实现具有至关重要的作用。在过去几十年的时间里,通过电纺、光刻、等离子处理等经典方法制备了各种各样的结构功能表面,实现在光、电、生物、化学等领域的广泛应用。然而为满足技术发展需求,实现表面微结构调控新策略的开发势不可挡。本文主要从分子扩散、材料内应力、外力的施加/释放,以及多种机制协同作用四个角度出发对聚合物表面结构调控的新策略进行介绍,并对今后聚合物表面结构调控的发展方向进行简要论述。Surface structure plays a vital role in the functionalization of polymer.In the past decades,various functional surfaces with diversified microstructures have been fabricated through electrospinning,lithography,plasma processing to achieve wide applications in optics,electronics,biology,chemistry and so on.However,there is still a huge demand to develop new strategies for regulating polymer’s surface microstructure to meet the growing requirements of economic and technological development.This review gives a brief instruction of current research on controlling surface structure from the perspectives of molecule diffusion,internal stress,external stress,and the cooperation of these different factors.Besides,the future development in controlling surface microstructure of polymer materials has been discussed.
