Abstract
Novel silver-containing nanocomposites based on 1-vinyl-1,2,4-triazole and vinyl acetate copolymer have been synthesised. The reduction of silver ions to the zero-valent state was carried out by a chemical method using the metal precursor AgNO3 and the reducing agent NaBH4. The copolymer obtained is established to exhibit a high stabilising ability by coordinating silver nanoparticles with the predominant participation of triazole and a partial participation of macromolecular acetate fragments. The physicochemical, optical and structural properties of the nanocomposites were analysed by IR and UV spectroscopy, transmission electron microscopy, X-ray diffraction and atomic absorption analysis. The obtained polymeric nanocomposites with silver nanoparticles sized 2-28 nm are characterised by a good water solubility, plasmon resonance absorption with a maximum of 420 nm and corresponding reflections on X-ray diffraction patterns. In addition, the nanocomposites exhibit antimicrobial activity against test microorganisms.
