PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, present exceptional chemical resistance and physical strength, rendering them highly suitable for various filtration uses. These films are often fabricated via wet inversion or electrospinning methods, leading in specific pore opening distributions. The basic hydrophobicity of PVDF can be modified through surface treatment or combining with water-attracting materials to broaden their effectiveness in aqueous separations such as nanofiltration and air separations, finding widespread use in wastewater treatment, biotechnology industries and energy storage devices.
