单向液体输送是实现医疗用高性能水分管理织物的关键。然而，实现单向液体传输同时满足其他要求，如抗菌功能、粘附性、低细胞毒性和足够的机械强度，仍然是一个挑战。在本研究中，通过静电纺丝和温和的交联过程，制备了既具有单向液体传输又具有抗菌活性的Janus纳米纤维膜。这种膜提供了连续的、自发的单向水传输，单向传输值(R)高达1483%。膜的抗菌率分别为99.2%和98.7%。科兰德·S。分别为金黄色，不加浸出抗菌剂。此外，它还具有高弹性和自粘性，这有助于其在一系列应用中的使用。这种多功能Janus纳米纤维膜的设计为开发新型排湿系统提供了新的策略，特别是在医用敷料领域。
Unidirectional liquid transport is critical in achieving high-performance moisture-management fabrics for medical care. However, realizing unidirectional liquid transport while simultaneously satisfying other requirements, such as antibacterial function, adhesiveness, low cytotoxicity, and adequate mechanical strength remains a challenge. In this study, Janus nanofibrous membranes exhibiting both unidirectional liquid transport and antibacterial activity were fabricated via electrospinning and a mild crosslinking procedure. This membrane provides continuous and spontaneous unidirectional water transport with a high one-way transport value (R) of 1483%. The membrane achieved antibacterial rates of 99.2% and 98.7% againstE. coliandS. aureus, respectively, without leaching antibacterial agents. In addition, it has high elasticity and self-adhesive properties, which facilitates its use in a range of applications. The design of this versatile Janus nanofibrous membrane provides a new strategy for developing novel moisture-wicking systems, particularly in the field of medical dressings.
