PVDF Membrane: A Comprehensive Guide

Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional material resistance and mechanical strength, making them extremely suitable for diverse filtration processes. These sheets are usually fabricated via phase inversion or track-etch methods, producing in unique pore size distributions. The natural hydrophobicity of PVDF can be changed through external treatment or blending with water-loving materials to broaden their effectiveness in aqueous separations such as nanofiltration and air separations, discovering widespread use in effluent treatment, pharmaceutical industries and power storage devices.
