PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, provide exceptional material resistance and physical strength, rendering them remarkably suitable for multiple filtration processes. These films are often fabricated via solvent inversion or track-etch methods, leading in unique pore size distributions. The basic hydrophobicity of PVDF can be altered through outer treatment or mixing with water-attracting materials to expand their functionality in aqueous separations such as microfiltration and vapor separations, discovering widespread use in effluent treatment, pharmaceutical industries and power storage devices.
