PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional process resistance and mechanical strength, causing them remarkably suitable for multiple filtration applications. These sheets are typically fabricated via solvent inversion or track-etch methods, producing in distinct pore diameter distributions. The natural hydrophobicity of PVDF can be changed through external treatment or mixing with water-loving materials to increase their effectiveness in aqueous separations such as nanofiltration and gas separations, discovering widespread use in effluent treatment, medical industries and power storage devices.
