PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, provide exceptional process resistance and physical strength, causing them remarkably suitable for diverse filtration processes. These sheets are usually fabricated via wet inversion or nonwoven methods, leading in distinct pore diameter distributions. The basic hydrophobicity of PVDF can be changed through external treatment or mixing with hydrophilic materials to expand their effectiveness in aqueous separations such as microfiltration and air separations, discovering widespread use in wastewater treatment, biotechnology industries and battery storage devices.
