Abstract:A solvent-free UV-initiated free-radical photopolymerization was employed to synthesize a series of cation-exchange membranes (CEMs) based on tertrabutylammonium styrene sulfonate (SSTBA). A novel casting solution was formed by dissolving SSTBA and an initiator in a mixture of styrene and trimethylolpropane triacrylate monomers without any organic solvent. Polymerization and membrane formation were simultaneously progressed to obtain the cross-linked CEMs within only 15 min, and the electrochemical properties … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
