PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional process resistance and physical strength, causing them extremely suitable for various filtration processes. These films are typically fabricated via wet inversion or electrospinning methods, leading in unique pore opening distributions. The inherent hydrophobicity of PVDF can be changed through surface treatment or mixing with water-attracting materials to expand their effectiveness in aqueous separations such as microfiltration and vapor separations, finding widespread use in water treatment, biotechnology industries and power storage devices.
