  Abstract

Membranes with the functions of waterproofness and breathability are of great interest due to their huge scientific and commercial value in many practical applications. However, designing such membranes with a desirable performance by simple and efficient fabrication process remains a tremendous challenge. Herein, novel binary structured composite fibrous membranes were developed for waterproof and breathable applications via simple one-step multi-jet electrospinning technology. This composite membranes were made up of polyvinylidene fluoride (PVDF) and polyacrylonitrile (PAN). PVDF was incorporated into the PAN fiber matrix as a modifier to improve the hydrophobic behavior of fibers. Meanwhile, PVDF microspheres/fibers were employed as building blocks to orderly embed in PAN/PVDF fiber framework, imparting the composite membranes with fluffy micro-nano hierarchical structures. Consequently, with the integrated features of robust hydrophobicity as well as elaborate fiber-microsphere binary structure, the resultant composite membranes exhibited synergistically modest waterproof and breathable performances with the hydrostatic pressure of 18.04 kPa, water vapor transmittance (WVT) rate of 4.65 kg m-2 d-1, and air permeability of 64.19 mm s-1. This simple preparation process and unique composite structure may provide a new insight to design and fabricate waterproof and breathable membranes for variously potential applications, including the protective clothing, separation membrane, and filter.
