PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, present exceptional chemical resistance and physical strength, making them remarkably suitable for various filtration processes. These sheets are typically fabricated via solvent inversion or track-etch methods, leading in specific pore opening distributions. The natural hydrophobicity of PVDF can be altered through surface treatment or mixing with hydrophilic materials to broaden their utility in liquid separations such as nanofiltration and air separations, locating widespread use in effluent treatment, biotechnology industries and power storage devices.
