PVDF Membrane: A Comprehensive Guide
Polyvinylidene difluoride membranes, commonly known as PVDF membranes, present exceptional chemical resistance and mechanical strength, making them extremely suitable for multiple filtration uses. These layers are often fabricated via wet inversion or track-etch methods, resulting in unique pore opening distributions. The natural hydrophobicity of PVDF can be changed through surface treatment or mixing with water-loving materials to expand their utility in liquid separations such as nanofiltration and gas separations, discovering widespread use in wastewater treatment, biotechnology industries and battery storage devices.
