“…These results suggest that N-halamine modi cation do not signi cantly possess cell toxicity; the results are in agreement with other reported results for similar studies. (Demir, Cerkez et al 2015;Demir, Broughton et al 2017;Grabchev, Staneva et al 2019;Gao, Su et al 2020) However, it is also assumed that the small toxicity observed in the present experiment may due to release or dissociation of Cl + into cell medium with time from N-halamine modi ed chitosan@AgNPs-NWFC. The release can be controlled by optimizing the chlorine contents at nonwoven cotton fabric and with repeated washing with water without affecting fabricated fabric properties.…”

Nonwoven cotton fabric has been fabricated and designed for antibacterial applications using low cost and ecofriendly precursors. The treatment of fabric with alkali leads to formation of active sites. The surfaces were dip coated with silver nanaoparticles and chitosan. The surface was chlorinated in next step to transform amide (N-H) groups in chitosan into N-halamine (N-Cl). The modified and unmodified surfaces of the nonwoven cotton fabric have been characterized by FTIR, SEM, and XRD. The active chlorine loading is measured with iodine/ sodium thiosulphate. The antimicrobial activity and cell toxicity assay were carried out with and without modifications of nonwoven cotton fabric. The antimicrobial efficacies of loaded fabric were evaluated against four bacterial species (Micrococcus lutes, Staphylococcus aurea, Enterobacter aerogenes, and E.coli). It was found that modified fabric exhibited superior efficiency against gram-positive and gram-negative bacterial strains as compared to their bulk counterparts upon exposure without destroying and affecting fabric nature. The overall process is economical for commercial purposes. The modified fabric can be used for antimicrobial, health, and food packaging industries, and in other biomedical applications.

“…[10,11] As one of the zwitterionic polymers with UCST type, poly(sulfobetaine) finds much interest by virtue of a high biocompatibility [12][13][14][15] and is broadly applied in the fields of biology and medicine. [11,[16][17][18][19] Importantly, apart from molecular variables such as the precise nature of the constitutional repeat unit or the molar mass, [3,[20][21][22][23] the TT of poly(sulfobetaine) is strongly affected by various factors, such as the solution concentration and the presence of salt. [20][21][24][25][26][27] Whereas thermoresponsive polymers with LCST type behavior were extensively studied in the last decade, fewer investigations focused on thermoresponsive polymers with UCST type behavior.…”

The kinetics of water transfer between the lower critical solution temperature (LCST) and upper critical solution temperature (UCST) thermoresponsive blocks in about 10 nm thin films of a diblock copolymer is monitored by in situ neutron reflectivity. The UCST‐exhibiting block in the copolymer consists of the zwitterionic poly(4‐((3‐methacrylamidopropyl)dimethylammonio)butane‐1‐sulfonate), abbreviated as PSBP. The LCST‐exhibiting block consists of the nonionic poly(N‐isopropylacrylamide), abbreviated as PNIPAM. The as‐prepared PSBP80‐b‐PNIPAM400 films feature a three‐layer structure, i.e., PNIPAM, mixed PNIPAM and PSBP, and PSBP. Both blocks have similar transition temperatures (TTs), namely around 32 °C for PNIPAM, and around 35 °C for PSBP, and with a two‐step heating protocol (20 °C to 40 °C and 40 °C to 80 °C), both TTs are passed. The response to such a thermal stimulus turns out to be complex. Besides a three‐step process (shrinkage, rearrangement, and reswelling), a continuous transfer of D2O from the PNIPAM to the PSBP block is observed. Due to the existence of both, LCST and UCST blocks in the PSBP80‐b‐PNIPAM400 film, the water transfer from the contracting PNIPAM, and mixed layers to the expanding PSBP layer occurs. Thus, the hydration kinetics and thermal response differ markedly from a thermoresponsive polymer film with a single LCST transition.

have been employed to endow surfaces with antimicrobial properties. Common strategies for developing antimicrobial textiles involve impregnating or coating the textiles with an active agent such as copper nanoparticles, copper oxide particles, copper sulfide, benzalkonium chloride, polybiguanide, iodine complexed with N-vinylpyrrolidone, salt coating, licorice root extract, silver nanoparticles, titanium dioxide, aluminum and aluminum oxide, anionic photosensitizers (rose Bengal and sodium 2-anthraquinone sulfate), zinc oxide, or graphene-based nanomaterials such as graphene oxides, nanofibers, nanosheets, and nanoparticles. [1,2,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] However, such strategies that rely on impregnating surfaces with antimicrobial agents are subject to leaching of the active compound, posing health risks to the wearer as well as causing environmental contamination through laundering and textile end-of-life disposal. [18] Covalent surface modification of textiles with antimicrobial agents can mitigate these risks.Covalent modification of antimicrobial polymers onto textile surfaces can be achieved by a variety of methods, such as graft polymerization via chemical free radical initiators, click chemistry, or radiation-induced graft polymerization. Radiation-induced graft polymerization can be accomplished by UV, plasma, electron beam or gamma radiation for surface modification with polar monomers, and offers several inherent advantages such
