PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional chemical resistance and physical strength, causing them extremely suitable for diverse filtration applications. These sheets are usually fabricated via wet inversion or electrospinning methods, leading in distinct pore opening distributions. The natural hydrophobicity of PVDF can be modified through outer treatment or mixing with water-attracting materials to expand their functionality in water-based separations such as microfiltration and vapor separations, locating widespread use in effluent treatment, medical industries and energy storage devices.
