Abstract Polyurethane (PU) is a polymer widely used in the biomedical field with excellent mechanical properties and good biocompatibility. However, it usually exhibits poor antibacterial properties for practical applications. Efforts are needed to improve the antibacterial activities of PU films for broader application prospect and added application values. In the present work, two PU films, TDI-P(E-co-T) and TDI-N-100-P(E-co-T), were prepared. Silver nanoparticles (AgNPs) were composited into the TDI-N-100-P(E-co-T) film for better mechanical properties and antibacterial activities, and resultant PU/AgNPs composite film was systematically characterized and studied. The as-prepared PU/AgNPs composite film exhibits much better antibacterial properties than the traditional PU membrane, exhibiting broader application prospect.

抗菌聚氨酯薄膜的合成及其性能

摘要 聚氨酯(PU)是一种广泛应用于生物医学领域的聚合物,具有优异的力学性能和良好的生物相容性。然而,它在实际应用中通常表现出较差的抗菌性能。需要努力提高PU薄膜的抗菌活性,以获得更广阔的应用前景和附加应用价值。在目前的工作中,制备了两种 PU 薄膜,TDI-P(E-co-T) 和 TDI-N-100-P(E-co-T)。将银纳米粒子 (AgNPs) 复合到 TDI-N-100-P(E-co-T) 薄膜中以获得更好的机械性能和抗菌活性,并对所得 PU/AgNPs 复合薄膜进行系统表征和研究。所制备的 PU/AgNPs 复合膜比传统 PU 膜具有更好的抗菌性能,具有更广阔的应用前景。
