PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, present exceptional material resistance and mechanical strength, rendering them remarkably suitable for diverse filtration processes. These sheets are typically fabricated via phase inversion or electrospinning methods, leading in specific pore diameter distributions. The natural hydrophobicity of PVDF can be modified through surface treatment or blending with water-loving materials to expand their functionality in aqueous separations such as microfiltration and gas separations, discovering widespread use in wastewater treatment, medical industries and energy storage devices.
