PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, present exceptional process resistance and mechanical strength, rendering them extremely suitable for multiple filtration processes. These sheets are often fabricated via wet inversion or track-etch methods, resulting in specific pore diameter distributions. The natural hydrophobicity of PVDF can be altered through surface treatment or combining with water-loving materials to increase their functionality in water-based separations such as nanofiltration and air separations, locating widespread use in water treatment, pharmaceutical industries and battery storage devices.
