✦ Synopsis

Pitch-based activated carbon fiber (ACF) supporting silver (ACF(Ag)) was prepared by preoxidization, carbonization, activation, immersion and decomposition processes. The structures, surface photographs and functional groups of the ACF and the ACF(Ag) were investigated.

The ACF exhibited increased oxygen-containing functional groups and decreased BET specific surface areas after supporting silver particles.

The ACF(Ag) with C-OH, C=O, -COOH and XOOAg groups showed strong adsorption and antibacterial activity against E. coli, which suggests it is a promising antibacterial material. However, ways of controlling the distribution of silver-particle size should be found before any practical application.

Although pitch-based carbon fibers can be melt spun, the flow characteristics of mesophase pitch make it extremely difficult to process. Mesophase pitch, like many fluids, can be non-Newtonian, but its viscosity is considerably more temperature sensitive than most melt-spun materials. In the present
