PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, offer exceptional process resistance and mechanical strength, making them extremely suitable for various filtration applications. These layers are typically fabricated via wet inversion or electrospinning methods, resulting in specific pore diameter distributions. The natural hydrophobicity of PVDF can be changed through surface treatment or combining with water-loving materials to expand their effectiveness in aqueous separations such as microfiltration and air separations, discovering widespread use in effluent treatment, medical industries and battery storage devices.
