Novel antibacterial cellulose acetate fibers modified with 2-fluoropyridine complexes

The complexes represented with the general formula [ML2Cl2] (L: 2-fluoropyridine; M: Ni (II), Cu (II), Co (II)) were synthesized and their structures were characterized via FT-IR and H-1 NMR techniques. Thermal properties of the complexes were also investigated via TG/DTA combined system under N-2 atmosphere. The complexes containing cellulose acetate (CA) micro/nano-fibers, which is a biocompatible and biodegradable polymer, were obtained via electrospinning technique. The fibers were characterized via FT-IR spectroscopy. FE-SEM images of the fibers were used to investigate their morphologies and for to determine the diameters of the fibers. Thermal properties of the fibers were investigated via TG/DTA combined system. Antibacterial studies of the complexes and fibers were investigated against the bacteria strains E. coli and Methyciline Resistant Staphylocaucus aureus via disc diffusion, broth microdilution and JIS L 1902: 2008, Testing method for antibacterial activity of textiles. Different levels Antibacterial activity was observed for all complexes and fibers. (C) 2019 Elsevier B.V. All rights reserved.
