Abstract

In this study, CNF (carbon nanofiber) was prepared with different process variables of electrospinning method. Morphology of CNF was observed by SEM, and main parameters to form the CNF were applied voltage, TCD, polymer concentration and heat treatment condition. Comparison of toluene removal efficiency, as applying the prepared CNF to electrodes of an electrolysis process, showed the direct effect of cathode on electrolysis as well as anode.

본 연구에서는 electrospinning method의 공정변수를 다르게 하여 CNF (carbon nanofiber)를 제조하였다. 제조된 CNF의 섬유의 형태, 직경 등의 변화를 SEM 분석을 통해 관찰하였으며 인가전압, TCD (tip to collecor distance), 고분자 용액의 농도, 열처리 단계가 CNF 물성을 형성함에 있어 주요한 영향인자임을 확인하였다. 또한 서로 다른 물성으로 제조된 CNF를 전기분해 공정의 전극으로 적용하여 toluene의 제거 효율을 비교하였고, 이를 통해 anode 뿐만 아니라 cathode 역시 전기분해 효율에 직접적인 영향을 미침을 확인하였다.
