PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, present exceptional process resistance and mechanical strength, making them remarkably suitable for multiple filtration processes. These layers are typically fabricated via wet inversion or track-etch methods, producing in distinct pore diameter distributions. The basic hydrophobicity of PVDF can be modified through surface treatment or mixing with hydrophilic materials to broaden their effectiveness in water-based separations such as nanofiltration and gas separations, discovering widespread use in effluent treatment, pharmaceutical industries and battery storage devices.
