PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, offer exceptional process resistance and physical strength, making them remarkably suitable for diverse filtration uses. These films are often fabricated via phase inversion or nonwoven methods, resulting in unique pore opening distributions. The natural hydrophobicity of PVDF can be changed through external treatment or mixing with hydrophilic materials to expand their functionality in aqueous separations such as nanofiltration and air separations, locating widespread use in effluent treatment, biotechnology industries and battery storage devices.
