PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, present exceptional material resistance and mechanical strength, making them remarkably suitable for multiple filtration processes. These films are usually fabricated via wet inversion or nonwoven methods, resulting in specific pore opening distributions. The inherent hydrophobicity of PVDF can be altered through surface treatment or combining with hydrophilic materials to increase their functionality in aqueous separations such as microfiltration and gas separations, discovering widespread use in effluent treatment, medical industries and battery storage devices.
