PVDF Membrane: A Comprehensive Guide

Polyvinylidene fluoride membranes, commonly known as PVDF membranes, provide exceptional chemical resistance and physical strength, making them extremely suitable for multiple filtration uses. These films are usually fabricated via phase inversion or track-etch methods, resulting in specific pore opening distributions. The basic hydrophobicity of PVDF can be modified through surface treatment or blending with hydrophilic materials to expand their effectiveness in water-based separations such as ultrafiltration and gas separations, finding widespread use in water treatment, pharmaceutical industries and power storage devices.
