PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, present exceptional material resistance and mechanical strength, making them highly suitable for various filtration processes. These layers are often fabricated via wet inversion or electrospinning methods, resulting in unique pore size distributions. The inherent hydrophobicity of PVDF can be changed through outer treatment or combining with water-attracting materials to increase their functionality in aqueous separations such as ultrafiltration and gas separations, locating widespread use in water treatment, medical industries and battery storage devices.
