Enhanced management and antifouling performance of a novel NiFe-LDH@MnO2/PVDF hybrid membrane for efficient oily wastewater treatment

Superhydrophilic PANI/Ag/TA@PVDF Composite Membrane with Antifouling Property for Oil–Water Separation

“…When water molecules fall on the surface of the hydrophilic membrane, a directional arrangement of the water molecules occurs by the influence of the polarity and electrostatic interactions between the hydrophilic groups, forming a dense and firmly bound hydration layer. The formation of the hydration layer can increase the distance between the pollutant and the membrane surface and reduce the adhesion of pollutants on the membrane surface. − Wu et al constructed a TA–Ti coordination network on the PVDF membrane through a simple layer-by-layer self-assembly process, which allows the oil droplets to first contact and interact with water on the surface, forming a hydration layer by combining a certain amount of water molecules to prevent the oil stains from depositing on the membrane surface. Photocatalytic oxidative degradation is a method that utilizes the strong oxidizing property of hydroxyl radicals ( • OH) generated by advanced oxidation technologies, including photocatalysis, catalytic wet oxidation, and Fenton/Fenton-like reactions, to achieve oxidative degradation of organic pollutants.…”
