PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, present exceptional chemical resistance and physical strength, causing them highly suitable for diverse filtration applications. These films are often fabricated via solvent inversion or track-etch methods, leading in distinct pore size distributions. The inherent hydrophobicity of PVDF can be altered through external treatment or combining with water-attracting materials to increase their utility in aqueous separations such as ultrafiltration and vapor separations, discovering widespread use in water treatment, biotechnology industries and power storage devices.
