PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride polymers membranes, commonly known as PVDF membranes, offer exceptional material resistance and mechanical strength, making them extremely suitable for multiple filtration uses. These sheets are typically fabricated via phase inversion or track-etch methods, producing in specific pore opening distributions. The inherent hydrophobicity of PVDF can be modified through outer treatment or combining with water-loving materials to expand their effectiveness in water-based separations such as microfiltration and gas separations, finding widespread use in effluent treatment, biotechnology industries and energy storage devices.
