Synthesis and characterization of novel biocidal cyclodextrin inclusion complexes grafted onto polyamide‐6 fabric by a redox method

Abstract

The synthesis of immobilized β‐cyclodextrin derivatives onto polyamide‐6 fabric is presented. These novel fabrics were prepared by graft‐copolymerization of glycidyl methacrylate (GMA) onto polyamide 6 fabric, using a chemical redox system K2S2O8/CuSO4·5H2O, followed by reaction of β‐cyclodextrins (CD) or monochlorotriazinyl (MCT β‐CD) with the GMA epoxy group. Some biocidal guests were complexed into CD cavity including p‐hydroxy benzoic acid, AgNO3–ethanolamine mixture, iodine, N,N‐diethyltoluamide (DETA), citronella, jasmine, and sweet basil. Characterization of the novel fabrics was done by Fourier transform infrared spectroscopy (IR), electron scanning microscopy (SEM), and thermo gravimetric analysis (TGA). The biocidal activity of the grafted fabrics was tested against five strains of microorganisms. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 99: 2586–2593, 2006

Surface modification of electrospun polyester nanofibers with cyclodextrin polymer for the removal of phenanthrene from aqueous solution

“…This indicated that the modification of PET nanofibers with CDP resulted in slightly higher thermal stability due to more energy requirement for decomposition of these samples having crosslinked structure. The increased thermal stability has been also observed for CD grafted polyamide 6 fabrics [38]. Moreover, the char yield was higher for PET/CDP nanofibers when compared to unmodified PET nanofibers possibly owing to the crosslinked CDP structure providing higher carbon residue upon burning.…”

Host–guest complex of cypermethrin with β-cyclodextrin: A spectroscopy and theoretical investigation

“…With these structural features, CDs are able to form host-guest complexes with hydrophobic molecules [3]. As a result of this function, the CDs have wide applications in textile function finishing [4][5][6][7][8][9][10][11][12][13][14].…”

Surface modification and preparation techniques for textile materials

“…An antimicrobial agent (benzoic acid), an odour-producing compound (vanillin), and an insect repellent pesticide (N, N-diethyl-meta-toluamide (DEET)) were some of the chemicals investigated for inclusion in these bound cyclodextrins. [43][44][45] The unique ability of cyclodextrins to form reversible complexes with a range of chemicals makes them attractive in a number of polymer-bound applications, including drug delivery, odour removal and fragrance applications.…”
