PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, offer exceptional material resistance and mechanical strength, causing them remarkably suitable for diverse filtration processes. These sheets are typically fabricated via wet inversion or electrospinning methods, resulting in specific pore opening distributions. The natural hydrophobicity of PVDF can be modified through outer treatment or combining with water-attracting materials to increase their effectiveness in liquid separations such as nanofiltration and gas separations, finding widespread use in wastewater treatment, pharmaceutical industries and energy storage devices.
