止血织物最常用于基线急救;然而，由于传统超亲水织物过度吸收血液而导致的不必要的失血被忽视。在此，首次提出了超疏水/超亲水Janus织物（一侧为超疏水，另一侧为超亲水）：超亲水部分吸收血液中的水以加速凝固，而超疏水部分防止血液进一步渗透。与普通面料相比，使用Janus面料可有效控制出血，减少50%以上的失血量，同时在很大程度上保持了透气性。所提出的原型甚至可以延长严重出血的大鼠模型的存活时间。这种通过简单地调节润湿性来减少失血的策略对于实际应用是有希望的。
Hemostatic fabrics are most commonly used in baseline emergency treatment; however, the unnecessary blood loss due to the excessive blood absorption by traditional superhydrophilic fabrics is overlooked. Herein, for the first time, superhydrophobic/superhydrophilic Janus fabrics (superhydrophobic on one side and superhydrophilic on the other) are proposed: the superhydrophilic part absorbs water in the blood to expedite the clotting while the superhydrophobic part prevents blood from further permeating. Compared with the common counterparts, effective bleeding control with reducing blood loss more than 50% can be achieved while the breathability largely remain by using Janus fabrics. The proposed prototypes can even prolong the survival time in the rat model with serious bleeding. This strategy for reducing blood loss via simply tuning wettability is promising for the practical applications.
