본 발명은 유동 대 장막 특성이 우수한 균형을 이루는 선택성 장막 매체를 산출하는, 수평균 나노섬유 직경이 200 nm 미만이고 평균 유동 기공 크기가 1000 nm 미만인 나노섬유 네트워크를 포함하는 미세 등급 자립형 나노웨브 및 나노섬유막에 관한 것이다. The present invention is directed toward a to fine-grade stand-alone nanoweb and nanofibrous membrane comprising a nanofiber network with a number average nanofiber diameter less than 200 nm and the mean flow pore size less than 1000 nm that yield the selective barrier medium with a superior balance of flow versus barrier properties.
