PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional process resistance and physical strength, causing them extremely suitable for diverse filtration uses. These films are typically fabricated via solvent inversion or track-etch methods, leading in specific pore size distributions. The natural hydrophobicity of PVDF can be altered through surface treatment or combining with water-attracting materials to broaden their functionality in water-based separations such as ultrafiltration and vapor separations, finding widespread use in water treatment, biotechnology industries and energy storage devices.
