  Abstract

Super-hydrophobic fibrous materials are highly sought after for improving protective performance and wearer comfort. However, developing durable superhydrophobic fabrics with exceptional moisture permeability and strong resistance to water penetration remains a considerable challenge. To address this, we propose a simple, yet efficient method for producing PVDF/FPU superhydrophobic nanofibers via direct coaxial electrospinning. The nanofibers exhibit stable hierarchical micro-nano-roughness, featuring numerous integrated nano-protrusions derived from the shell solution. Further modification with low-surface-energy FPU enhances the super-hydrophobicity. Additionally, the PVDF/FPU nanofibrous membranes possess a finely structured hydrophobic porous network, characterized by small pore size and high porosity, which ensures outstanding water penetration resistance while Maintaining high moisture permeability. As a consequence, the resultant membranes display remarkable comprehensive waterproof and breathable properties with high water vapor transmission rate of 9.3 kg m-2 d-1, excellent hydrostatic pressure of 94 kPa, as well as good superhydrophobic property with water contact angle of 153°, suggesting great promise as exceptional candidates for personal protection and comfort management.
