dc.description.abstract | U ovom radu diskutovana je mogućnost sinteze nanolistića na bazi Cu na pamučnoj tkanini koji bi pružili željeni nivo antimikrobne aktivnosti. Da bi se obezbedio dovoljan broj karboksilnih grupa za vezivanje Cu2+ -jona iz rastvora soli prekursora pamučna tkanina je selektivno oksidisana u dvostepenom procesu sa NaIO4 i NaClO2. Sorbovani Cu2+ -joni su redukovani galnom kiselinom. FESEM i XRD analize su pokazale da nanolistići CuO organizovani u fine slojeve ravnomerno pokrivaju površinu vlakana. Što je veća početna koncentracija NaIO4, veći je broj karboksilnih grupa i posledično količina sintetisanih nanolistića CuO. Razvijeni tekstilni nanokompoziti su pokazali odličnu antibakterijsku aktivnost prema Gram-negativnoj bakteriji Escherichia Coli i Gram-pozitivnoj bakteriji Staphylococcus aureus, kao i zadovoljavajuću antifungalnu aktivnost prema kvascu Candida albicans. | sr |
dc.description.abstract | This study discussed the possibility of synthesizing Cu-based nanosheets on cotton fabric which could provide desired level of antimicrobial activity. In order to ensure a sufficient number of carboxyl groups that could efficiently bind Cu2+-ions from precursor salt solution, cotton fabric was selectively oxidized in two-step process with NaIO4 and NaClO2. Sorbed Cu2+-ions were reduced with gallic acid. FESEM and XRD analyses revealed that CuO nanosheets organized in fine layers evenly covered the surface of cotton fibers. The larger the initial concentration of NaIO4, the larger the number of carboxyl groups and consequently the amounts of synthesized CuO nanosheets. Fabricated textile nanocomposites exhibited excellent antibacterial activity against Gram-negative bacterium Escherichia Coli and Gram-positive bacterium Staphylococcus aureus as well as satisfactory antifungal activity against yeast Candida albicans. | sr |
