Abstract

In this study, waste polyethylene terephthalate (PET) was recycled to produce a support and then polyetherimide (PEI) was used for environmentally friendly organic solvent nanofiltration. The prepared composite membrane was first prepared by electrospinning a PET support, then casted on the support using PEI having excellent solvent resistance, and organic solvent nanoparticles using a Non-solvent Induced Phase Separation (NIPS) method. A filtration membrane was prepared. First, the fiber diameter and tensile strength of the PET scaffold prepared prior to membrane fabrication were identified through morphology analysis, and the optimal scaffold for the organic solvent nanofiltration membrane was identified. Afterward, the PET/PEI composite membrane prepared was checked for the DEA removal rate of Congo red having a molecular weight of 697 g/mol in ethanol to understand the performance as an organic solvent nanofiltration membrane according to the concentration of PEI. Finally, the removal rate of Congo red was 90% or more.

본 연구는 투명 폐 Polyethylene Terephthalate (PET)병을 재활용하여 지지체를 제조 후에 Polyetherimide (PEI)를 이용하여 친환경적인 유기용매나노여과막 (Organic Solvent Nanofiltration)에 이용하고자 하였다. 제조된 복합막은 먼저, PET 지지체는 전기방사를 통해 제조를 하였으며 이후 내용매성이 우수한 PEI를 이용하여 지지체 위에 캐스팅하였고 비용매 유도상분리(Non-solvent Induced Phase Separation, NIPS) 방법을 이용하여 유기용매나노여과막을 제조하였다. 먼저 막제조에 앞서 제조된 PET 지지체는 모폴로지 분석을 통해 섬유의 직경과 인장강도를 파악하였으며 유기용매나노여과막의 최적 지지체 조건을 확인하였다. 이후 제조된 PET/PEI 복합막은 PEI의 농도에 따른 유기용매나노여과막으로서의 성능을 파악하기 위하여 에탄올에 분자량 697 g/mol을 가지는 Congo red의 제거율을 확인하였으며 최종으로 Congo red의 제거율이 90%이상의 제거율을 가지는 최적의 PET/PEI 복합막을 확인하였다.
