PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional process resistance and structural strength, rendering them highly suitable for various filtration processes. These films are typically fabricated via solvent inversion or track-etch methods, resulting in unique pore opening distributions. The inherent hydrophobicity of PVDF can be changed through surface treatment or combining with water-loving materials to increase their effectiveness in water-based separations such as ultrafiltration and gas separations, finding widespread use in wastewater treatment, pharmaceutical industries and battery storage devices.
