PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, provide exceptional process resistance and physical strength, rendering them highly suitable for multiple filtration processes. These sheets are typically fabricated via solvent inversion or nonwoven methods, producing in specific pore diameter distributions. The natural hydrophobicity of PVDF can be changed through outer treatment or mixing with water-attracting materials to broaden their utility in liquid separations such as microfiltration and gas separations, locating widespread use in water treatment, pharmaceutical industries and energy storage devices.
