PVDF Membrane: A Comprehensive Guide
Polyvinylidene fluoride membranes, commonly known as PVDF membranes, offer exceptional process resistance and structural strength, making them highly suitable for multiple filtration uses. These sheets are usually fabricated via wet inversion or nonwoven methods, resulting in specific pore size distributions. The basic hydrophobicity of PVDF can be changed through external treatment or mixing with water-attracting materials to expand their functionality in liquid separations such as microfiltration and gas separations, discovering widespread use in wastewater treatment, medical industries and power storage devices.
