“…20 The advantages of N-halamine-carrying materials include high biocidal efficacy, long-term stability, high durability, simple rechargeability and low toxicity with little environmental concern. [29][30][31][32] Previous studies demonstrated the detoxification ability of N-halamine-containing fabrics against certain carbamate and organophosphorus pesticides via oxidizing sulfide and thiophosphate groups, respectively. [25][26][27][28] Furthermore, active N-halamine structures can oxidize alcohols to ketones, sulfides to sulfoxides and sulfones, as well as cyanides to carbon dioxide and ammonium in aqueous conditions.…”

Novel composite membranes with poly(vinyl alcohol-co-ethylene-g-diallylmelamine) (PVA-co-PE-g-DAM) nanofibers layered on poly(propylene-g-diallylmelamine) (PP-g-DAM) meltblown nonwoven fabric were successfully developed as lightweight and breathable protective materials with chemical and biological decontamination functions. By controlling levels of coated nanofibers, three nanofibrous membranes with similar surface morphology, hydrophilicity and transport properties were prepared. The N-halamine precursor moieties in the membrane matrices can be converted to active N-halamine structures with a diluted sodium hypochlorite solution, and the active chlorine content on the membranes is rechargeable and durable. The chlorinated nanofibrous membranes demonstrated very powerful and rapid biocidal effects against both E. coli and S. aureus by contact, as well as excellent disinfection effect to wet bacterial penetration through the membrane. Furthermore, the efficient chemical detoxification functions of the halamine nanofibrous membranes were also observed by a total decontamination of aldicarb, a carbamate pesticide, within 30 min. These PVA-co-PE-g-DAM nanofiber composite membranes can serve as ideal ultra-light filtering media for chemical and biological protective clothing materials.

Styrene-divinylbenzene copolymer containing N-bromosulphonamide groups as sodium salt, [P]-SO 2 NBrNa, can be viewed as a high molecular weight redox polymer mimicking its low molecular weight analogue: Bromamine-T. The stability of this copolymer in acidic media has not been studied in detail to date. This paper reports on studies of the reaction between the copolymer and aqueous FeSO 4 solution conducted in a series of batch and column experiments. It was found that pH \3.0 results in transition of active bromine from -SO 2 NBr -groups to the solution, followed by oxidation of Fe 2? ions to Fe 3? ions by elemental bromine. In reaction media of pH [3.0, active bromine remains bound to the functional groups, facilitating application of this copolymer as an effective oxidant in column processes running in weakly acidic reaction media. Results of the present work provide evidence that -SO 2 NBr -functional groups of the copolymer can stably exist in acidic form which is in contrast to the behaviour of the low molecular weight analogue (N-bromo-p-toluenesulphonic acid does not occur as a pure chemical compound).
