PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional material resistance and mechanical strength, causing them extremely suitable for multiple filtration uses. These sheets are usually fabricated via solvent inversion or electrospinning methods, producing in specific pore opening distributions. The inherent hydrophobicity of PVDF can be changed through surface treatment or blending with water-attracting materials to increase their effectiveness in liquid separations such as ultrafiltration and air separations, discovering widespread use in water treatment, biotechnology industries and energy storage devices.
