PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, provide exceptional material resistance and structural strength, rendering them highly suitable for various filtration processes. These films are typically fabricated via wet inversion or track-etch methods, resulting in distinct pore size distributions. The inherent hydrophobicity of PVDF can be altered through surface treatment or mixing with water-attracting materials to expand their functionality in aqueous separations such as nanofiltration and gas separations, locating widespread use in water treatment, medical industries and battery storage devices.
