摘要:

应用静电纺丝装置制备出锦纶6/TiO2复合超细纤维非织造布,采用扫描电子显微镜、能谱分析仪、红外光谱仪探讨其微观形貌、结构,通过抗菌性能测试验证其功能性,以期用于新型过滤膜、防护服等功能型复合材料。结果表明:TEOS助剂的添加实现了TiO2纳米颗粒的改性,有利于较好形貌的锦纶6/TiO2纤维的形成;当TiO2在锦纶6/TiO2超细纤维中质量分数为6%和8%时,静电纺纤维尺寸较均匀,珠状物较少;随质量分数增加,锦纶6/TiO2纤维膜对大肠杆菌的抗菌效果有所提高,当达到10%和12%时,其抗菌率均在80%以上。

Abstract:

The electrospinning technique was adopted to fabricate nylon6/TiO2 ultrafine fibers. Scanning electron microscope (SEM), transmission electron microscopy (TEM), and fourier transform infrared spectroscopy (FTIR) were used to characterize the morphology and microstructure of the resultant nanofibers. Furthermore, in order to develop a novel functional composite material for filter film and protective clothing, the antibacterial performance of the nonwoven mats against escherichia coli was also measured. It indicates that the TEOS additives are useful for modifying TiO2 nanoparticles which can be evenly dispersed in the solution, and this is very important for the preparation of nylon6/TiO2 fibers with fine morphology. When the mass fraction of TiO2 is 6% and 8%, the fibers are uniform with the least beads. As the fraction is increased to 10% and 12%, the antibacterial efficiency of the nylon6/TiO2 membrane is over 80%.
