PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, provide exceptional material resistance and mechanical strength, rendering them extremely suitable for various filtration uses. These sheets are usually fabricated via solvent inversion or electrospinning methods, resulting in unique pore diameter distributions. The inherent hydrophobicity of PVDF can be modified through outer treatment or combining with water-loving materials to increase their utility in aqueous separations such as nanofiltration and air separations, locating widespread use in wastewater treatment, medical industries and battery storage devices.
