PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, provide exceptional chemical resistance and physical strength, making them remarkably suitable for various filtration processes. These sheets are usually fabricated via wet inversion or electrospinning methods, resulting in specific pore opening distributions. The basic hydrophobicity of PVDF can be changed through external treatment or combining with hydrophilic materials to broaden their effectiveness in water-based separations such as microfiltration and air separations, locating widespread use in water treatment, pharmaceutical industries and battery storage devices.
