PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, provide exceptional material resistance and structural strength, rendering them remarkably suitable for diverse filtration applications. These sheets are often fabricated via wet inversion or electrospinning methods, producing in distinct pore diameter distributions. The basic hydrophobicity of PVDF can be changed through external treatment or blending with hydrophilic materials to expand their effectiveness in liquid separations such as microfiltration and gas separations, finding widespread use in water treatment, medical industries and energy storage devices.
