Hydrophobic and breathable nanofiber membranes have attracted considerable attention owing to their applications in various fields. In this study, we fabricated superhydrophobic and breathable nanofiber membranes using solution blow spinning. We optimized the spinning process parameters by analyzing their effects on the structure and properties of the nanofiber membranes. And the nanofiber membranes achieved superhydrophobicity through hydrophobic modification treatment. The average fiber diameter and pore size of the obtained membrane were 0.51 and 13.65 μm, respectively. The membranes exhibited superhydrophobicity, breathability, and mechanical properties: water vapor transmission of 12.88 kg/m 2 /day, air permeability of 10.97 mm/s, water contact angle of 150.92°, maximum tensile stress of 5.36 MPa, and maximum elongation at break of 12.27%. Additionally, we studied the impact of heat treatment on the nanofiber membranes. The membranes prepared in this study can be applied to protective garments, outdoor clothing, antifouling materials, etc. Because of its relatively higher production efficiency, solution blow spinning is a prospective method for producing functional nanofibers.

Recently, waterproof and breathable materials have attracted extensive attention and have been used in a broad range of applications such as clothing, sports equipment, medical hygiene products, and other fields. In this study, an efficient chemical modification method was suggested to prepare polyurethane/SiO2 nanofibrous membranes with superhydrophobicity and durability. A polyurethane emulsion was treated with 4,4′-methylenebis(phenyl isocyanate) and 3-aminopropyltriethoxysilane. This emulsion process was combined with the emulsion electrospinning technique and a hydrothermal-assisted sol–gel process to prepare superhydrophobic polyurethane nanofibrous membranes. The final polyurethane/SiO2 nanofibrous membranes exhibited a hydrostatic pressure of 8.02 kPa, an air permeability of 3.89 mms–1, and a water vapor transmission rate of 10.12 kg m–2 d–1. Results also showed that the water contact angle of the nanofibrous membranes reached 154°, and the stress and strain were 5.3 MPa and 198%, respectively. In addition, the adhesion between SiO2 and the PU nanofibrous membranes was high, and the weight loss rate of SiO2 remained at approximately 9.72% after the ultrasonic cleaning time exceeded 24 h. These results suggested that the PU/SiO2 nanofibrous membranes were expected to provide a new perspective for waterproofing and moisture permeability.

“…Unfortunately, due to the complex post‐process, PDMS cannot be evenly distributed within the membranes 16 . PU and PAN, subjecting to the poor hydrophobicity of these raw polymers, the obtained membranes exhibit inferior waterproof performance, 17 thus, it is necessary to use hydrophobic substances, such as, particles and waterproofing agents to modify the surface 18–20 . However, the following problem is that particles and other materials are very likely to fall off under conditions, such as, membrane deformation, resulting in a decrease in performance.…”

In this work, a waterproof and breathable nanofibrous membrane with thermal‐regulated performance and exhibits excellent mechanical property is fabricated by coaxial electrospinning. The fiber shell is consisted of polyvinylidene fluoride (PVDF) and polyvinyl butyral (PVB), and the core is octadecane. First, well‐performed waterproof and breathable membranes are obtained by optimizing its morphology and pore structure. Then octadecane is loaded into the fibers in the form of core by coaxial electrospinning, though it gives the membranes a thermal regulating function, but the drawback is the sacrifice of overall properties. Thus, carbon nanotubes are loaded into the shell and studied, finally, the best membrane has a comprehensive performance with hydrostatic pressure of 59.2 kPa, water vapor transmission rate (WVTR) of 7.846 kg m−2 d−1, latent heat of 50.1 J g−1, as well as excellent tensile strength of 20.2 MPa, which shows its certain reference significance to the synthesis of multifunctional membrane.
