PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, offer exceptional chemical resistance and structural strength, causing them highly suitable for various filtration processes. These sheets are typically fabricated via phase inversion or track-etch methods, producing in distinct pore opening distributions. The natural hydrophobicity of PVDF can be changed through surface treatment or combining with water-loving materials to increase their effectiveness in aqueous separations such as nanofiltration and vapor separations, finding widespread use in effluent treatment, biotechnology industries and energy storage devices.
