초록

본 연구에서는 전기방사를 이용하여 PS의 취성을 개선하고자 내충격성이 우수한 HIPS와 가교제 DVB를 혼합하여 방사한 후 가교와 술폰화 반응을 통해 HIPS 이온교환 나노섬유를 제조하였다. 또한, 이들을 FT-IR, XPS, 함수율, 이온교환 용량, SEM 및 접촉각으로 나노섬유의 기본특성을 확인하였다. FT-IR 및 XPS 구조분석 결과, HIPS 나노섬유는 술폰화 시간이 지남에 따라 -SO3H기의 도입이 증가하는 것을 확인할 수 있었다. 또한 술폰화 시간이 지남에 따라 섬유의 친수성이 증가하여 DVB 함량이 7.5 wt%, 술폰화 시간이 200분일 때 함수율과 이온교환용량은 최대 75.6%, 2.67 meq/g으로 나타났다.

In this study, it was prepared for nanofiber with high impact polystyrene(HIPS). HIPS is able to crosslinking after electrospinning with crosslinking agent and it could overcome brittle characteristics of polystyrene(PS). After thermal crosslinking, HIPS nanofiber was sulfonated by sulfuric acid. It was investigated FT-IR, XPS, water uptake, ion exchange capacity(IEC), SEM, and contact angle. According to the result of FT-IR and XPS, it was increased due to introduce the hydrophilic group(SO3H) in the HIPS nanofiber. The highest water uptake and IEC were 75.6%, 2.67 meq/g at 120 min sulfonation time with 7.5 wt% DVB.
