PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, offer exceptional material resistance and structural strength, making them extremely suitable for multiple filtration uses. These films are often fabricated via solvent inversion or nonwoven methods, leading in distinct pore size distributions. The basic hydrophobicity of PVDF can be modified through surface treatment or combining with water-loving materials to broaden their utility in liquid separations such as microfiltration and air separations, discovering widespread use in water treatment, pharmaceutical industries and power storage devices.
