초록
전기방사법을 이용하여 폴리(비닐 알코올)(poly(vinyl alcohol), PVA)/수분산 폴리우레탄(waterborne polyurethane, WBPU)/montmorillonite clay(MMT) 나노복합섬유를 제조하고 특성을 분석하였다. Scanning electron microscopy(SEM), transmission electron microscopy(TEM), X선 회절, thermal gravimetric analyzer(TGA) 의 분석장비들을 이용하여 제조된 나노복합섬유의 형태와 구조적, 열적특성을 확인한 결과, 평균직경이 600∼900nm인 나노복합섬유들이 성공적으로 제조되었으며, MMT가 나노섬유 내에 완전박리되어 기존의 고분자 나노섬유에 비해 열적성질이 향상되었음을 확인할 수 있었다. 본 연구를 통해 제조된 나노복합섬유는 친수성이고 생체친화적인 재료들을 이용하여 제조되었으며, 의료 분야를 비롯하여 의류 및 산업용 코팅제, 필터 등의 분야로 이용이 가능할 것으로 보인다.
Poly(vinyl alcohol) (PVA)/waterborne polyurethane (WBPU)/montmorillonite clay (MMT) nanocomposite nanofibers were prepared using electrospinning technique of aqueous solutions. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction and thermal gravimetric analyzer were used to characterize the morphology and properties of the nanocomposite nanofibers. Since PVA, WBPU and MMT are hydrophilic, non-toxic and biocompatible materials, these nanocomposite nanofibers can be used for filter and medical industries as wound dressing materials, antimicrobial filters, etc.
Keywords:poly(vinyl alcohol)(PVA);waterborne polyurethane(WBPU);montmorillonite(MMT);nanocomposite;nanofiber.
