Preparation and characterization of Nylon6 TiO₂ hybrid ultrafine fibers

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 Cu^{2 +} does in the opposite way. The photocatalytic antibacterial efficiency of the Nylon6-TiO₂ fibers shows fine performance, while Nylon6-TiO₂ membrane, doped by the Cu^{2 +} and (or) Ag ⁺, displays good antibacterial one without the catalytic effect.
