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 various filtration processes. These films are often fabricated via wet inversion or nonwoven methods, resulting in distinct pore opening distributions. The basic hydrophobicity of PVDF can be modified through external treatment or combining with hydrophilic materials to broaden their effectiveness in liquid separations such as ultrafiltration and vapor separations, locating widespread use in effluent treatment, pharmaceutical industries and power storage devices.
