Abstract
Electrospinning is a simple, effective method for nanofiber nanofabrication using polymers. Poly(vinyl alcohol) (PVA) is a water-soluble and nontoxic polymer with good chemical and thermal stability. Electrospun PVA nanofibrous non-woven fabrics are expected to have significant applications in the area of membranes for filtration and biomedical engineering and protective clothes, etc. Stable electrospinning of PVA aqueous solution, however, was hampered by surface solidification causing splashing of the droplet. In this study, PVA nanofiber was continuously produced using coaxial electrospinning where PVA solution in the core was covered by poly(ethylene oxide) solution in the sheath preventing PVA surface drying. The effects of molecular weight and degree of hydrolysis on the morphology of electrospun PVA nanofiber were investigated. Also, PVA nanofiber was chemically cross-linked using poly(acrylic acid) (PAA) to improve its water resistance and avoid discoloration.

전기방사법은 나노섬유를 제조하는 효율적이고 간편한 방법이다. 폴리(비닐 알코올)(PVA)은 화학적·열적 특성이 우수하고 인체에 무해한 수용성 고분자로서, 이를 이용한 나노섬유는 필터, 의료공학용 멤브레인, 기능성 의류 등과 같은 분야에 응용될 것으로 기대된다. 그러나 PVA 수용액의 전기방사 시 표면응고현상으로 인해 노즐이 막히거나 액적이 튀어 연속적으로 나노섬유를 제조하기 어렵다는 문제점이 있다. 본 연구에서는 폴리에틸렌옥사이드(PEO) 수용액이 PVA 수용액을 감싸 표면응고를 억제하는 형태의 공축전기방사로 안정적이고 연속적인 PVA 나노섬유 제조가 가능하였다. PVA의 검화도 및 분자량에 따른 core-sheath 나노섬유의 형태 및 구조 변화를 연구하였고, PEO만을 선택적으로 제거하였다. 또한 폴리아크릴산(PAA)을 사용한 가교로 습윤환경에서 PVA 나노섬유의 응용성을 개선하였다.
