ABSTRACT Conventionally, electrospun thin‐film composite (TFC) membranes used in protective clothing are fabricated on the basis of an electrospinning substrate coated with a nonporous hydrophilic polymer layer. However, incompatibility common coating solvents inertia materials requires that support material should be surface‐modified to promote crosslinking dense and porous layers. In this study, we attempted fabricate novel TFC membrane for use by one‐step deposition poly(vinylidene fluoride) (PVDF) nanofibers onto dense, thermoplastic polyester elastomer (TPEE) via electrospinning. The proposed approach has advantage no need further surface modification membrane. optimized exhibited better tensile strength than TPEE film. testing results moisture resistance show new had comparatively high water vapor transmission rate, notwithstanding value was slightly lower single‐layered Simultaneously, resistance‐in‐series model based Henis–Tripodi's explaining permeation behavior proposed. values predicted analyzed were good agreement these experimental data.
