PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, provide exceptional chemical resistance and structural strength, causing them highly suitable for various filtration applications. These sheets are usually fabricated via phase inversion or track-etch methods, resulting in unique pore diameter distributions. The natural hydrophobicity of PVDF can be altered through surface treatment or blending with hydrophilic materials to expand their utility in aqueous separations such as microfiltration and gas separations, finding widespread use in wastewater treatment, medical industries and energy storage devices.
