In recent years, surface patterning of membranes has been explored as a new strategy to modify surface properties of polymeric membranes. A variety of methods including template-based micromolding and direct printing have been developed for effective fabrication of surface-patterned membranes. In this review, we compare the underlying pattern replication mechanisms and the advantages and challenges associated with the range of different fabrication methods. The presence of the surface patterns, when properly created, can enlarge the active surface/interfacial area, create more effective conduction pathways, and enhance the hydrodynamic effects. These effects can be harnessed for improving membrane performance for a wide range of applications.

近年来，膜的表面图案化已被研究为改变聚合物膜的表面性质的新策略。为了有效地制造表面图案化的膜，已经开发了多种方法，包括基于模板的微成型和直接印刷。在这篇综述中，我们比较了底层的图案复制机制以及与不同制造方法范围相关的优势和挑战。如果适当创建表面图案，则可以增加有效表面/界面面积，创建更有效的传导路径并增强流体动力效果。可以利用这些效果来提高膜的性能，以适应广泛的应用。
