PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, present exceptional chemical resistance and physical strength, causing them extremely suitable for diverse filtration processes. These films are often fabricated via phase inversion or track-etch methods, resulting in distinct pore opening distributions. The natural hydrophobicity of PVDF can be modified through external treatment or mixing with water-attracting materials to broaden their utility in aqueous separations such as nanofiltration and vapor separations, finding widespread use in water treatment, medical industries and power storage devices.
