Activated carbon fibers(ACF) were prepared from stabilized polyacronitrile(PAN) fiber by chemical activation with KOH. Yield, specific surface area and elemental content of ACFs with the different activation conditions such as concentration of KOH and heat treatment temperature were evaluated. The specific surface area of ACF was proportional to the concentration of KOH solution used for activation of ACF. The specific surface area of ACF increased remarkably above 800℃ of heat treatment temperature. Yield of ACF which is chemically activated was improved several times compared to ACF which is activated physically.
