KOH를 이용한 활성탄소섬유의 제조
Preparation of Acti- vated Carbon Fiber by Chemical Activation with KOH
초록
안정화 Polyacronitrile(PAN) 섬유를 원료로 KOH를 이용하여 화학적 방법으로 활성탄소섬유를 제조하였다. KOH용액의 농도, 열처리온도의 변화에 따라 제조된 활성탄소섬유의 수율, 비표면적 및 원소분석을 조사하였다. KOH 농도 증가에 따라 비표면적이 증가하였고 열처리 온도는 800℃이상에서 급격히 비표면적의 상승을 나타내었다. 물리적 활성화에 비해 수배의 수율이 향상되었다.
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 which is chemically activated was im- proved several times compared to ACF which is activated physically.
