PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, present exceptional process resistance and physical strength, making them extremely suitable for various filtration processes. These sheets are typically fabricated via phase inversion or track-etch methods, leading in specific pore opening distributions. The natural hydrophobicity of PVDF can be modified through external treatment or combining with water-attracting materials to increase their effectiveness in water-based separations such as nanofiltration and gas separations, locating widespread use in wastewater treatment, medical industries and energy storage devices.
