PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, provide exceptional material resistance and mechanical strength, causing them extremely suitable for diverse filtration processes. These layers are often fabricated via phase inversion or electrospinning methods, resulting in specific pore size distributions. The natural hydrophobicity of PVDF can be changed through external treatment or mixing with hydrophilic materials to increase their functionality in water-based separations such as microfiltration and air separations, discovering widespread use in wastewater treatment, medical industries and power storage devices.
