PVDF Membrane: A Comprehensive Guide

Polyvinylidene fluoride membranes, commonly known as PVDF membranes, present exceptional chemical resistance and structural strength, making them remarkably suitable for multiple filtration processes. These layers are usually fabricated via solvent inversion or track-etch methods, resulting in specific pore size distributions. The basic hydrophobicity of PVDF can be modified through outer treatment or combining with water-attracting materials to broaden their functionality in aqueous separations such as ultrafiltration and gas separations, finding widespread use in water treatment, pharmaceutical industries and battery storage devices.
