PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, offer exceptional chemical resistance and structural strength, rendering them highly suitable for multiple filtration uses. These sheets are often fabricated via wet inversion or nonwoven methods, producing in distinct pore opening distributions. The inherent hydrophobicity of PVDF can be altered through outer treatment or mixing with water-attracting materials to expand their utility in aqueous separations such as microfiltration and air separations, locating widespread use in effluent treatment, pharmaceutical industries and energy storage devices.
