PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, provide exceptional process resistance and mechanical strength, causing them highly suitable for various filtration applications. These layers are typically fabricated via solvent inversion or nonwoven methods, resulting in unique pore opening distributions. The natural hydrophobicity of PVDF can be modified through surface treatment or mixing with hydrophilic materials to expand their utility in liquid separations such as nanofiltration and vapor separations, finding widespread use in water treatment, biotechnology industries and power storage devices.
