In this study, an N-chloramide-modified reactive copolymer, chlorinated poly (4-vinylbenzenesulfonamide-co-methyl methacrylate) (PVMCl), was designed and synthesized for rapid and efficient detoxification of sulfur mustard (HD, 2-bis(2chloroethyl) sulfide) under ambient conditions. The detoxification rate of HD was up to 95% in 1 h, and HD was decomposed completely within 5 h by PVMCl both in aqueous solution and solid phase. The product characterization revealed the essential role of surface N-chloramide groups for the selective oxidation of HD. Furthermore, the self-decontamination nonwoven mat was successfully fabricated by electrospinning, which showed a satisfactory decontamination rate and long-term effect against HD.
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.
