摘要

Improving the nanofiltration(NF)performance of membrane-based treatment is conducive to promoting environmental water recycling and addressing water resource depletion.Combinations of light,electricity,and heat with traditional techniques of preparing membranes should optimize membrane performance.Interfacial polymerization and photopolymerization were integrated to construct a photopolymerized thin-film composite NF membrane with a ridged surface morphology.Under visible light initiation,2-acrylamido-2-methyl-l-propane-sulfonic acid was crosslinked with the polyamide network.The control effects of light on the membrane surface and physicochemical properties were revealed via infrared thermal images and response surface methodology.To present the diffusion motion of piperazine molecules,molecular dynamics simulations were implemented.Through density functional theory simulations,the crosslinking mechanism of the photoinduced NF network was identified and verified.The surface physicochemical characteristics and perm-selectivity performance were systematically illustrated.The photopolymerized membrane outperformed the pristine in permeability and selective separation competence;without degradation of solute repulsion,the water permeation was enhanced to 33.5 L m~(-2)h~(-1)bar~(-1),6.6 times that of the initial membrane.In addition,the removal of organic contaminants and antifouling capacities were improved.This work represents a novel lead for applying sustainable resources in constructing high-performance membranes for environmental challenges.
