PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional material resistance and structural strength, causing them highly suitable for multiple filtration applications. These sheets are often fabricated via wet inversion or electrospinning methods, leading in unique pore diameter distributions. The natural hydrophobicity of PVDF can be changed through external treatment or combining with hydrophilic materials to broaden their functionality in aqueous separations such as microfiltration and vapor separations, finding widespread use in wastewater treatment, biotechnology industries and power storage devices.
