PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, provide exceptional chemical resistance and physical strength, rendering them highly suitable for multiple filtration processes. These layers are usually fabricated via wet inversion or electrospinning methods, leading in specific pore diameter distributions. The basic hydrophobicity of PVDF can be modified through outer treatment or blending with water-attracting materials to broaden their effectiveness in aqueous separations such as nanofiltration and air separations, discovering widespread use in water treatment, medical industries and battery storage devices.
