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%.
