ABSTRACT Electrospun mats have many possible applications in which it is important to control their interaction with water: when used as separation membranes, superhydrophobic mats can remove oil from water, whereas when used as scaffolds for tissue engineering, hydrophilic mats present better cell affinity. Frequently, however, the surface properties of the polymer fibers that compose the mat need to be modified and tuned. This review covers the main surface modification techniques used to change the water wettability of mats produced by electrospinning. Some basic aspects of the electrospinning process and wetting theories are presented as a starting point for the discussion, highlighting the common wetting switching mechanism found in highly porous structures like electrospun mats. The surface modification techniques are then classified as post-treatments or one-step modification during electrospinning. The fundamental aspects of each technique are followed by a discussion emphasizing their technical advantages and drawbacks.

表面改性以控制电纺垫的水润湿性

摘要电纺垫有许多可能的应用，其中控制它们与水的相互作用很重要：当用作分离膜时，超疏水垫可以去除水中的油，而当用作组织工程的支架时，亲水垫表现出更好的细胞亲和力。然而，构成垫子的聚合物纤维的表面特性经常需要修改和调整。这篇综述涵盖了用于改变静电纺丝垫的水润湿性的主要表面改性技术。提出了静电纺丝过程和润湿理论的一些基本方面作为讨论的起点，重点介绍了在电纺垫等高度多孔结构中发现的常见润湿转换机制。然后将表面改性技术归类为静电纺丝过程中的后处理或一步改性。每种技术的基本方面之后是讨论，强调它们的技术优点和缺点。
