Summary: | The present invention relates to a multilayer composite nanofibrous membrane and a method for preparing the same. More specifically, the present invention relates to a multilayer composite nanofibrous membrane prepared by forming a microporous hydrophilic coating layer on a nanofiber layer with weak hydrophobicity, and a method for preparing the same. The multilayer composite nanofibrous membrane according to the present invention can improve the spontaneous one-way mobility of moisture from the nanofiber layer to the hydrophilic coating layer by a capillary phenomenon, and enables the control of the moisture transfer performance by adjusting the UV irradiation time.
본 발명은 다층형 복합나노섬유막 및 그 제조방법에 관한 것으로, 보다 상세하게는 약한 소수성을 갖는 나노섬유층 상에 미세다공형의 친수성 코팅층을 형성함으로써 모세관 현상에 의해 나노섬유층에서 친수성 코팅층으로의 자발적인 일방향 수분 이동성을 향상시킬 수 있고, 자외선 조사시간을 조절하여 수분전달 성능 제어가 가능한 다층형 복합나노섬유막 및 그 제조방법에 관한 것이다. |
