摘要 角蛋白基的纳米纤维膜在创面敷料领域展现出重要应用潜力。然而,如何通过材料设计实现同时维持纤维膜的亲水性和水稳定性,仍是当前研究的难点。为制备孔隙率高、水稳定性优异和亲水性良好的纳米纤维膜,本研究以聚乙烯醇(PVA)、羊毛角蛋白(KE)、抗菌因子苯扎氯铵(BKC)为原料,利用静电纺丝工艺和热交联,构建了在常温下和40 ℃的水浴下稳定的三组分纳米纤维膜,并对纤维膜的表观形貌、化学结构、热稳定性、亲水性能和孔隙率等相关指标进行测试。结果表明,6%(质量分数)PVA组别中,PVA、KE、BKC质量比为1∶0.25∶0.1的组别与二组分纤维膜相比综合性能最优。PVA/KE/BKC纤维膜的水稳定性、亲水性能可通过纺丝液的配比和热交联的方法进行调节,有望应用于伤口敷料领域。

Abstract: Keratin-based nanofibrous membranes hold significant promise for wound dressings; however, developing fibrous membranes that simulta-neously maintain good hydrophilicity and water stability remains challenging. To fabricate nanofiber membranes with high porosity, favorable water stability, and good hydrophilicity, this study utilized polyvinyl alcohol (PVA), wool keratin (KE) and antibacterial agent benzalkonium chloride (BKC) as raw materials. A three-component nanofiber membrane stable in water at room temperature and 40 ℃ was constructed via electrospinning followed by thermal crosslinking. The membranes’ apparent morphology, chemical structure, thermal stability, wettability and porosity were characterized. Results demonstrated that, compared to two-component fiber membranes, the membrane prepared from a 6wt% PVA solution with a PVA/KE/BKC mass ratio of 1∶0.25∶0.1 exhibited optimal water stability while maintaining good hydrophilicity. The water stability and wettability of the PVA/KE/BKC fiber membrane can be tailored by adjusting the spinning solution composition and the thermal crosslinking method, indicating its potential application in wound dressings.
