PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, offer exceptional material resistance and mechanical strength, rendering them highly suitable for various filtration applications. These layers are typically fabricated via solvent inversion or track-etch methods, resulting in distinct pore size distributions. The natural hydrophobicity of PVDF can be altered through surface treatment or combining with water-loving materials to expand their functionality in water-based separations such as ultrafiltration and air separations, finding widespread use in water treatment, medical industries and energy storage devices.
