A new and straightforward route was proposed to incorporate silver nanoparticles (Ag NPs) into the surface of polyurethane nanofibers (PU NFs). Uniform distribution of in situ formed Ag NPs on the surface of PU NFs was achieved by adding AgNO and tannic acid in a PU solution prior to the electrospinning process. The synthesized nanofiber mats were characterized with state-of-the-art techniques and antibacterial performances were tested against and bacteria. The cytocompatibility and cell behavior were studied by using fibroblast cells. Following this preparation route, Ag/PU NFs can be obtained with excellent antibacterial performance, thus making them appropriate for various applications such as water filtration, wound dressings, etc.
提出了一种将银纳米颗粒（Ag NPs）掺入聚氨酯纳米纤维（PU NFs）表面的新颖且直接的方法。通过在静电纺丝过程之前向PU溶液中添加AgNO₃和单宁酸，实现了原位形成的Ag NPs在PU NFs表面的均匀分布。用先进技术对合成的纳米纤维垫进行了表征，并测试了其对大肠杆菌和金黄色葡萄球菌的抗菌性能。使用成纤维细胞研究了细胞相容性和细胞行为。按照这种制备方法，可以获得具有优异抗菌性能的Ag/PU NFs，因此使其适用于水过滤、伤口敷料等各种应用。
