PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, offer exceptional material resistance and physical strength, making them remarkably suitable for diverse filtration processes. These films are often fabricated via solvent inversion or nonwoven methods, leading in distinct pore opening distributions. The basic hydrophobicity of PVDF can be modified through surface treatment or combining with water-attracting materials to increase their functionality in aqueous separations such as nanofiltration and air separations, locating widespread use in wastewater treatment, pharmaceutical industries and battery storage devices.
