Abstract

In this study, nano fibers with various physical properties were materialized by using a variety of polymers [PAN (Polyacrylonitrile), PU (Polyuretane), PSU (Polysulfone)] which are raw materials of dope solution manufactured for electrospinning and solvents [NMP (N-methyl-2 pyrrolidone), DMF (Dimethylformamide)] and evaluated characteristics of their flux and SS (Suspended Solids) separation and then ascertained application of manufactured fibers as separation membrane for water treatment. In this study, analysis of surface of manufactured material was carried out through SEM analysis to ascertain the cause of flux and SS separation performance by checking diameter, uniformity and straightness of fiber. If additive is used in manufacturing nano fiber water treatment separation membrane, it is expected to solve problems such as membrane fouling and mechanical strength and to be used as basic factor for manufacturing separation membrane with catalyst function added.

본 연구에서는 전기방사를 통해 제조되는 dope solution의 원료인 다양한 Polymer [PAN (Polyacrylonitrile), PU (Polyuretane), PSU (Polysulfone)]와 용매[NMP (N-methyl-2 pyrrolidone), DMF (Dimethylformamide)]를 이용하여 다양한 물성의 나노섬유 물질을 구현하고, 이의 flux 특성과 SS (Suspended Solids) 분리 성능을 평가하여 제조된 섬유의 수처리 분리막으로서의 적용성을 확인하였다. 또한 SEM 분석을 통해 제조된 소재의 표면 분석을 수행하여, 섬유의 직경, 균일성 및 직진성 확인을 통해 flux, SS 분리 성능의 원인을 확인하였다. 추후 나노섬유 수처리 분리막 제조공정에서의 첨가제 투입을 통해 막 파울링, 기계적 강도 등의 문제를 해결할 수 있을 것으로 예상되며, 촉매 기능이 첨가된 수처리용 분리막 제조를 위한 기초 인자로써 활용될 수 있을 것으로 기대된다.
