Abstract

With the development of industry, fine dust is causing difficulties in various fields such as environment, health, and life, and a large amount of pollutants generated from human social activities are emerging as a serious environmental problem due to air pollution. Therefore, in this study, activated carbon was added to remove fine dust and volatile organic compounds by spinning cellulose acetate polymer fibers on a silicon support using the electrospinning method. By varying the activated carbon ratio and electrospinning time, the fine dust blocking effect and toluene adsorption performance were confirmed according to the activated carbon ratio and filter thickness. As a result, it was shown that the particles were effectively blocked with the increase in the electrospinning time due to the filter thickness increase. Adsorbed amount of toluene was increased with increase in activated carbon amount. Light transmittance was decrease with increase in electrospinning time, showing that there were light transmittance in filters electrospun for 20~30 minutes.

산업이 발달함에 따라 미세먼지는 환경, 건강, 생활 등 다양한 분야에서 문제를 일으키고 있으며, 특히 대기오염에 의해 발생되는 미세먼지는 심각한 환경문제로 대두되고 있다. 따라서 본 연구에서는 전기방사 기술을 적용하여 실리콘 지지체에 셀룰로스아세테이트 고분자 섬유를 방사하여 미세입자를 차단하고, 활성탄 입자를 첨가하여 휘발성유기 화합물을 제거하고자 하였다. 활성탄 비율과 전기방사 시간을 달리하여 활성탄 비율, 필터 두께에 따른 미세먼지 차단효과, 톨루엔 흡착 성능을 분석하였다. 그 결과 전기방사시간이 증가함에 따라 1~3 ㎛ 크기의 입자가 효과적으로 차단되었으며, 활성탄의 양이 0%에서 5%로 증가함에 따라 톨루엔 흡착량이 증가하는 것으로 나타났다. 전기방사 시간이 길어질 경우 필터 두께 증가로 인해 빛 투과가 현저히 떨어졌으며, 20~30분 전기방사한 필터의 경우 빛이 투과하여 창문 필터 적용 가능성을 보여주었다.
