Abstract:

采用静电纺丝法制备了Nylon6-TiO2及其杂化超细纤维无纺布。使用SEM、TEM和FTIR等方法探讨了其微观形貌、结构,并通过抗菌性能方法验证其抗菌性能与不同金属离子掺杂Nylon6-TiO2纤维膜的关系。结果表明:Ag+的掺杂可改善电纺纤维的形貌特征,使纤维尺寸均匀,珠状物减少;Cu2+的掺杂降低了Nylon6-TiO2的纤维形貌。同时,纳米TiO2的添加实现了Nylon6-TiO2纤维膜在光催化条件下对大肠杆菌和金黄色葡萄球菌的抗菌效果,Cu2+和(或)Ag+的掺杂使纤维膜在无光催化条件下具有一定抗菌效果,为开发新一代过滤膜、防护服及医疗器械等复合材料奠定基础。
