PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, present exceptional material resistance and structural strength, making them remarkably suitable for diverse filtration applications. These films are usually fabricated via phase inversion or track-etch methods, resulting in distinct pore opening distributions. The natural hydrophobicity of PVDF can be altered through surface treatment or blending with water-loving materials to increase their functionality in aqueous separations such as nanofiltration and gas separations, discovering widespread use in water treatment, biotechnology industries and power storage devices.
