In this paper, PC/TiO2 hybrid nonwovens were prepared by electrospinning. By means of scanning electron microscopy(SEM), transmission electron microscopy(TEM), fourier transform infrared spectroscopy(FTIR), and other methods, their morphology, structure, and antibacterial performance were investigated. Furthermore, the relationship between the antibacterial ability of the nonwoven mats for Escherichia coli and the type of the hybrid metal ion was also explored. It showed that the Cu2+ or Ag+ doping could improve the morphology of electrospun fibers and reduce their side beads and such an effect was stronger when combined doping of Cu2+and Ag+. Moreover, it implied that the light sensor-type antibacterial agent TiO2 was successfully modified by the contact-type antibacterial agent; therefore, the doped fiber membrane had some antibacterial function under no light catalytic conditions.
