Abstract

A new type of antibacterial and absorbent acrylonitrile (AN)-vinylidene chloride (VDC) copolymer fibers were used as base
materials for preparing activated carbon fiber (ACF) absorbents by means of oxidation, carbonization, and activation in a continuous semi-open high temperature furnace. The PAN/VDC fibers were spun from the mixtures of AN-VDC copolymer-dimethylformamide solution and silver-impregnated activated carbon (Ag-AC) powders. The activated carbon fibers pre-pared by PAN/VDC fibers of various contents of Ag-AC were studied. Scanning electron microscopy was used to observe the surface morphology of the ACFs. The BET specific surface areas of the ACFs were determined from N  adsorption 2 isotherms; and the absorbability was measured by methylene blue (MB) absorption. The results showed that the ACFs prepared by PAN/PVDC fibers containing Ag-AC have greater favorable adsorbing ability. The silver content was greater than 0.24wt% in the ACFs, which can provide antibacterial efficacy.
