Waterproof and breathable membranes are critical for protective textiles, filtration, and wearable applications. However, balancing water resistance with vapor permeability remains challenging. This study investigates the morphological effects of electrospun polyacrylonitrile/polyvinylidene fluoride (PAN/PVDF) nanofiber membranes on their waterproofness, breathability, and mechanical integrity. Varying polymer concentration can control fiber diameter (224–1379 nm) and bead formation, influencing membrane properties. Increasing fiber diameter enhances mechanical strength, with Young's modulus rising from 22.5 MPa to 34.1 MPa. All fabricated membranes exhibit excellent waterproofness, while the larger, bead-free fibers possess improved water vapor transmission and slightly reduced air permeability. FTIR analysis confirms consistent chemical composition across samples. These findings demonstrate that nanofiber morphology can be tailored to optimize performance, offering valuable insights for the development of multifunctional membranes for environmental, industrial, and wearable use. © 2025 Korean Physical Society
