Abstract: PURPOSE: A method for producing an activated carbon fiber is provided to improve the absorbing property for various absorbing materials, and to continuously show the absorbing characteristic by a surface functional group formed on the surface of the activated carbon fiber. CONSTITUTION: An activated carbon fiber is produced by carbonizing under a nitrogen atmosphere at 900, 1000, 1100, 1200, and 1300°C for 30-150minutes used to a general production of carbon fiber. The content of carbon is increased by removing non-carbon components, and the spot-like pored structure on the surface of the carbon fiber is developed with the discharge of non-carbon components by introducing the carbonizing process before an oxy PAN (Poly Acrylo Nitrile) fiber and/of its carbon fiber of high intensity are activated. And the absorbing property is improved by showing the uniform structure and the distribution of pore formed micro pores under 20Angstroms.

Abstract: 본발명은잘 발달된표면구조와우수한흡착성능을갖는활성탄소섬유를산성또는알칼리성등의전해용액, 바람직하게는인산(HPO) 또는탄산칼륨(KCO) 전해용액중에서전기화학적표면처리를행하여탄소체표면에관능기를도입한, 고기능성활성탄소섬유의제조방법에관한것이다. 이러한탄소체표면에도입된관능기는활성탄소섬유의표면구조및 흡착성능에영향을주지않는반면에, 표면극성의발달과더불어우수한이온교환특성을부여하므로, 제조된활성탄소섬유는기상및 액상에서의오염원뿐만아니라극성을갖는유ㆍ무기중금속오염원에대한선택적흡착성능이대폭향상되는특징을갖는다.
