“…A pad-dry-cure approach was used to immobilize ACHT onto cellulose. Our previous studies have demonstrated that this method could provide high reaction efficiency in a relatively short period of time [44]. In this treatment, cotton fabrics were dipped into the ACHT solution, padded through a laboratory wringer (Atlas Electric Devices Co., Chicago, IL) to 100% wet pickup (three repeats), wrapped in aluminum foil, and cured in an oven at 120°C for 20 min.…”

In this study, 2-amino-4-chloro-6-hydroxy-s-triazine (ACHT) was synthesized through controlled hydrolysis of 2-amino-4,6-dichloro-s-triazine (ADCT). A simple paddry-cure approach was employed to immobilize ACHT onto cellulosic fibrous materials. After treatment with diluted chlorine bleach, the covalently bound ACHT moieties were transformed into chloromelamines. The structures of the samples were fully characterized with NMR, UV/VIS, DSC, TG, iodometric titration and elemental analyses. The chloromelamine-based fibrous materials provided potent, durable, and rechargeable biocidal functions against bacteria (including multi-drug resistant species), yeasts, viruses, and bacterial spores. SEM studies demonstrated that the new fibrous materials could effectively prevent the formation of biofilms, and controlled release investigations in vitro suggested that the biocidal activities were bioresponsive. Biocidal mechanisms of the chloromelamine-based fibrous materials were further discussed.

“…The chlorine content of the treated fabrics was determined by iodimetric titration [44]. Briefly, about 0.5 g of the chlorinated ACHT-immobilized fabrics was cut into small pieces and then added into 40 ml of absolute ethanol containing 2 g KI.…”

“…This process consumes chlorines, but the consumed chlorines can be readily recharged by another halogenation treatment 16–18. Thanks to these attractive properties, N ‐halamine structures have been incorporated into different materials to provide potent, durable, and rechargeable biocidal functions against a broad spectrum of microorganisms 17, 19–31…”

Upon chlorine bleach treatment, amino groups in chitosan were transformed into N-halamine structures. The transformation was confirmed by UV/VIS, XPS, DSC, and TGA evaluation and iodimetric titration. The N-halalmine-based chitosan provided total kill of 10(8)-10(9) colony forming units (CFU/mL) of E. coli (gram-negative bacteria) and S. aureus (gram-positive bacteria) in 10 and 60 min, respectively. SEM observations demonstrated that the chlorinated chitosan effectively prevented the formation of bacterial biofilms. The antimicrobial activity and bio film controlling function were stable for longer than 1 month; when the functions were lost due to extensive use and/or prolonged storage, they could be readily recharged by another bleach treatment. The antimicrobial mechanism was also discussed.

“…One of the first studies on this domain reported the covalent bond of a reactive melamine derivative, 2-amino-4-chloro-6-hydroxy-s-triazine, onto cotton cellulose through nucleophilic substitution (Sun et al 2005). Upon chlorine bleaching treatment, the covalently bound melamine derivative moieties could be transformed into chloromelamine derivatives, affording strong, longlasting, and rechargeable antibacterial activity against 10 6 -10 7 CFU/mL of drug-resistant Gramnegative (S. aureus spp.)…”

This chapter aims at presenting a comprehensive overview of the latest advances in the development of antibacterial materials based on chitosan, cellulose, and starch, which being the most abundant polysaccharides have a high potential to be explored in large variety of applications (e.g., food or biomedical fields).Owing to its intrinsic antibacterial and film-forming properties, chitosan can be directly used to create antibacterial materials. Thus, the first part of this chapter focuses mainly on the factors affecting its inherent bioactivity and the strategies potentially used to enhance it, in order to broaden chitosan-based materials applicability. Then the strategies developed to impart antibacterial properties to cellulose and starch, mainly through chemical modification or combination with bioactive natural and synthetic components and polymers as well as with metal and metal oxide nanoparticles, were screened in detail, pointing out their antibacterial profile and prospective applications.
