PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, present exceptional chemical resistance and mechanical strength, rendering them highly suitable for multiple filtration processes. These layers are typically fabricated via wet inversion or track-etch methods, leading in distinct pore size distributions. The inherent hydrophobicity of PVDF can be modified through external treatment or mixing with water-loving materials to expand their utility in aqueous separations such as nanofiltration and vapor separations, discovering widespread use in water treatment, biotechnology industries and battery storage devices.
