PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, provide exceptional process resistance and physical strength, making them remarkably suitable for multiple filtration processes. These films are often fabricated via phase inversion or electrospinning methods, producing in distinct pore size distributions. The natural hydrophobicity of PVDF can be changed through outer treatment or mixing with hydrophilic materials to expand their effectiveness in water-based separations such as microfiltration and air separations, finding widespread use in effluent treatment, medical industries and battery storage devices.
