The feasibility of PVDF (polyvinylidene fluoride), as a novel waterproof and moisture-permeable material, to substitute PTFE (polytetrafluoroethylene) for manufacturing civil high-performance textiles was discussed. The work was focused on the design of casting solution composition (including solvent, additives, and polymer), possible methods to produce durably binded coated micropore membrane fabrics as well as their influences on membrane properties.
