  Abstract

With the growing demand of multifunction membranes with water vapor transmission and breathable performances in many fields, design of multifunction membranes with facile fabrication is crucial and challenging. In this work, a highly breathable bi-layered polyurethanes—polyacrylonitrile/cellulose acetate (PU-PAN/CA) membrane with outstanding water vapor transmission and excellent mechanical property was fabricated by electrospinning. And then, the bi-layered PU-PAN/CA nanofibrous membranes were characterized using SEM, FTIR, tensile stress, water contact angle, air permeability, water vapor permeability and moisture management tester to evaluate the performance. The prepared PU-PAN/CA membrane has a comprehensive performance by adjusting the CA ratio of the PAN/CA layer and electrospinning time of PU layer with breathable of 21.81 mm s-1, water vapor transmission (WVT) rate of 12.18 kg m-2 day-1, and tensile strength of 8.90 MPa, which shows its certain reference significance to the prepared of multifunctional membrane. At the end, the performance of prepared membrane was compared with other membranes. The successful preparation of such interesting bi-layered membranes could provide enlighten for the preparation of other functional fibrous materials, especially in oil/water, directional water transport and moisture-wicking clothing.
