초록
전기방사법을 이용하여 향나무 추출물을 함유하는 폴리우레탄 나노섬유를 제조하였다. 폴리우레탄은 적절한 성분 배합 제조가 가능하므로 다양한 산업 분야, 의료 분야에서 널리 이용되고 있는 소재이다. 향나무는 항암, 항균, 항곰팡이, 항바이러스성을 가진 것으로 알려져 있다. 향나무 추출물의 다양한 농도(0.25, 0.5, 1, 1.5wt.%)를 포함하는 폴리우레탄 복합 나노섬유를 제조하였다. 나노섬유를 제조하기 위한 다양한 공정변수(방사용액의 농도, TCD, 인가전압)의 변화를 살펴보았다. 실험을 통해 얻어진 PU방사용액의 적정 전기방사 조건은, 방사용액의 농도가 12wt%, 인가전압은 8kV, TCD는 15cm로 나타났다. SEM을 통한 향나무 추출물을 함유하는 나노섬유의 직경은 435nm∼547nm였으며, 향나무 추출물의 함량이 증가함에 따라 나노섬유의 평균직경은 감소하는 것으로 나타났다. 개발된 나노웹은 의료 소재, 보호복 소재, 항균필터 소재 등으로의 활용이 기대된다.
Abstract
The uniform nanofibers of polyurethane with different contents of Juniperus Chinensis extracts were successfully prepared by electrospinning method. Polyurethane is widely used as functional polymers in the industrials, medicalfield as their properties can be tailor-made by adjusting their compositions. Juniperus Chinensis has been reported for anti-tumor, anti-bacterial, anti-fungal, and anti-viral activities. PU/Juniperus Chinensis extracts compositenanofibers were produced at different Juniperus Chinensis extracts concentrations (0.25, 0.5, 1, 1.5wt.%). The effects of the major parameters in electrospinning process such as tip to collector distance (TCD), voltage, polymerconcentration on the average diameter of electrospun nanoweb were investigated. As results, 12wt% PU solution concentration, 8kV applied voltage and 15cm tip to collector distance were identified as optimum conditions forelectrospinning the composite nanofibers. The diameter and morphology of the nanocomposite nanofibers were confirmed by a scanning electron microscopy (SEM). The resulting fibers exhibited a uniform diameter rangingfrom 435nm∼547nm. It has been found that the average diameters of fibers decreased by the adding of Juniperus Chinensis extracts. These nanowebs can be used for medical materials, protective clothing, and antimicrobial filters.
