A　green　anion　exchange　membrane　for　electrodialysis　desalination　was　synthesized　using　a　solvent-free　photo-polymerization　approach.　Vinylbenzyl　chloride　(monomer),　tripropylene　glycol　diacrylate　(crosslinker),　and　photoinitiator　were　mixed　and　subjected　to　UV　polymerization　for　20　min　to　create　the　base　membrane,　followed　by　positive　charge　modification　with　1-methylimidazole.　This　method　avoids　organic　solvents,　offering　economic　and　environmental　benefits.　By　adjusting　the　degrees　of　crosslinking　and　positive　charge,　precise　control　over　the　membrane＇s　microstructure　and　properties　was　achieved.　The　optimized　membrane　showed　an　area　resistance　of　1.67　Ω　cm2　and　a　transport　number　of　0.956,　demonstrating　exceptional　electrochemical　performance.　Under　comparable　conditions,　the　optimized　membrane　improved　the　NaCl　removal　rate　by　11.47　%,　increased　current　efficiency　by　10.61　%,　and　reduced　energy　consumption　by　16.75　%　compared　to　commercial　AMV　membrane,　highlighting　its　potential　for　scalable　seawater　desalination　through　electrodialysis.　©　2024　Elsevier　B.V.
