The polyurethane (PU) nanofibrous web prepared by electrospinning was coated with aqueous polydopamine solution to improve its functional properties. Through the scanning electron microscope, it was confirmed that polydopamine was uniformly coated on the PU web, and further surface analysis was performed. The physical properties such as moisture permeability, tensile strength, and the like before and after the coating were not changed, but the antimicrobial activity and the UV blocking performance were improved. Therefore, the PU nanofibrous web coated with polydopamine is expected to be used as a substitute for high functional Gore-Tex membrane.
전기방사에 의해 제조된 폴리우레탄(PU) 나노섬유 웹의 기능성을 향상시키기 위하여 폴리도파민 수용액으로 코팅하였다. 전자주사현미경을 통하여 PU 웹에 폴리도파민이 균일하게 코팅되었음을 확인하였으며, 추가적으로 표면 분석을 수행하였다. 코팅 전후의 수분 및 공기 투과능, 인장강도 등의 물리적 특성변화는 나타나지 않았고 항균성과 자외선 차단능을 향상시키는 결과를 보였다. 따라서 폴리도파민으로 코팅된 PU 나노섬유 웹이 고기능성 고어텍스 필름의 대체품으로 적용가능성이 있을 것으로 기대된다.
