PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, offer exceptional material resistance and mechanical strength, rendering them remarkably suitable for multiple filtration processes. These sheets are usually fabricated via solvent inversion or nonwoven methods, producing in specific pore opening distributions. The natural hydrophobicity of PVDF can be modified through surface treatment or combining with water-attracting materials to increase their utility in liquid separations such as ultrafiltration and vapor separations, locating widespread use in water treatment, pharmaceutical industries and energy storage devices.
