PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, present exceptional chemical resistance and physical strength, making them remarkably suitable for multiple filtration applications. These layers are typically fabricated via phase inversion or nonwoven methods, resulting in unique pore diameter distributions. The basic hydrophobicity of PVDF can be modified through external treatment or mixing with water-loving materials to expand their utility in liquid separations such as ultrafiltration and air separations, finding widespread use in wastewater treatment, medical industries and energy storage devices.
