초록

액상에서의 오존 산화 반응에 의해 활성탄소섬유 표면 산소의 함량은 17.0 wt%에서 22.4 wt%로 증가하였고, 수소의 함량은 1.9 wt%에서 2.7 wt%로 증가하였다. 오존 산화 개시제를 달리하여 처리하면 활성탄소섬유에 생성되는 관능기들과 총산도값을 조절할 수 있었다. 오존 처리되지 않은 활성탄소섬유의 총산도값은 0.631 meq./g인데 비하여, 1 M NaOH 수용액을 개시제로 오존 처리된 활성탄소섬유는 0.762 meq./g, 1 M H2O2 수용액을 개시제로 오존 처리된 활성탄소섬유는 0.824 meq./g로 증가하였고, 특히 phenol그룹이 크게 증가하였다. NaOH로 처리하면 phenol그룹만 증가하였고, H2O2로 처리하면 phenol그룹이 많이, carboxyl그룹이 약간 증가하였다.

The oxygen and the hydrogen contents of activated carbon fibers increased from 17.0 wt% and 1.9 wt% to 22.4 wt% and 2.7 wt% by oxidation with ozone in liquid phase. The amount of functional groups and total acidity could be controlled with initiators of ozone decomposition reactions. The total acidity of ACF ozone treated in NaOH solution and H2O2 solution increased to 0.762 meq./g and 0.824 meq./g respectively, while that of non-treated ACF was 0.631 meq./g, and particularly the phenolic group increased. The phenolic group only was developed when ACF was treated in NaOH solution, large amount of phenolic group and some carboxylic group were developed when ACF was treated in H2O2 solution.
