Description
Summary:Polyacrylonitrile（PAN）-based activated carbon fiber（PACF） supporting nano-ZnO（PACF/nano-ZnO） was prepared by spin, pretreatment, carbonization, and KOH chemical activation at an activation temperature of 950℃ for 40 min. Nano-ZnO content, distribution and antibacterial properties of the PACF/nano-ZnO were studied. The pore structure and surface properties of the PACF/nano-ZnO were studied by Brunauer-Emmett-Teller（BET）, N2/77 K isothermal adsorption. The specific surface area increased markedly after the activation process and it was several hundred times greater than that before the process. The PACF/nano-ZnO shows a strong adsorption for Staphylococ- cus aureus（S, aureus） and Escherichia coli（E, coli） and antibacterial activity against them. As an experimental result, antibacterial properties of PACF/nano-ZnO increased with increasing the concentration of nano-ZnO panicles, which suggests it is a promising antibacterial material.
