Rechargeable Potent Anti‐Viral Cotton Grafted with a New Quaternized N‐Chloramine

Abstract

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

The Rise of Electroactive Materials in Face Masks for Preventing Virus Infections

“…Currently, natural virus inhibitors, − metals/metal oxides/particles or ions, − metal–organic frameworks, − small organic molecules, − salts, − and carbon-based materials − have been added to air filters to inactivate viruses or bacteria retained by filtration. In addition, researchers have systematically reviewed the current development of antiviral masks in terms of effectiveness, importance, preparation process, testing, and characterization, environmental impact, and development trend .…”
