PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, provide exceptional process resistance and structural strength, rendering them remarkably suitable for diverse filtration uses. These films are usually fabricated via solvent inversion or nonwoven methods, resulting in specific pore opening distributions. The inherent hydrophobicity of PVDF can be modified through outer treatment or blending with hydrophilic materials to increase their effectiveness in water-based separations such as nanofiltration and vapor separations, finding widespread use in water treatment, biotechnology industries and energy storage devices.
