PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, present exceptional material resistance and structural strength, causing them remarkably suitable for diverse filtration uses. These sheets are usually fabricated via solvent inversion or track-etch methods, resulting in distinct pore diameter distributions. The basic hydrophobicity of PVDF can be altered through external treatment or combining with water-loving materials to expand their functionality in liquid separations such as nanofiltration and vapor separations, locating widespread use in water treatment, pharmaceutical industries and energy storage devices.
