PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional process resistance and physical strength, rendering them remarkably suitable for various filtration processes. These films are often fabricated via wet inversion or track-etch methods, resulting in specific pore size distributions. The basic hydrophobicity of PVDF can be altered through outer treatment or combining with water-loving materials to expand their effectiveness in liquid separations such as nanofiltration and air separations, locating widespread use in water treatment, medical industries and energy storage devices.
