Activated-Carbon Fibers With High Surface Areas

This proposal is directed to the preparation of high-surface-area (HSA) activated-carbon fibers that are suitable for the Army's lightweight chemical-protective combat uniforms. The overall goal of the proposed program is to develop a domestic source of activated-carbon fibers having surface areas greater than 1500 m2/g. Our approach begins with a novel method of preparing polymeric precursor fibers, which is based on existing technolog now being commercialized for other applications by Bend Research. The precursor fibers will then be heat-treated, carbonized, and activated using existing, proven techniques, we believe this process offers a high probability for success. Successful completion of hte Phase I program and a subsequent Phase II should lead to domestic production of activated-carbon fibers that are technically superior to those currently available overseas and that are less expensive to produce. During a Phase II program we would collaborate with a textile manufacturer and/or carbon-fiber manufacturer to facilitate the early commercial-scale production of the improved fibers.
