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。
Nylon6 nanofibers containing TiO2 nanoparticles and Ag or Cu-doped composite nanoribbons were synthesized by a facile combination of a mixed electrospinning technique.By means of SEM,TEM and FTIR,the nanofibers were subsequently characterized.The antibacterial performance of the nonwoven mats was also measured.The results show that the morphology of the electrospun fibers is improved by dopping of Ag ＋,while the Cu2 ＋ does in the opposite way.The photocatalytic antibacterial efficiency of the Nylon6-TiO2 fibers shows fine performance,while Nylon6-TiO2 membrane,doped by the Cu2 ＋ and（or） Ag ＋,displays good antibacterial one without the catalytic effect.
