Silver polymer complexes as precursors of nanocomposites based on polymers of 1-vinyl-1,2,4-triazole

Abstract Bioactive silver-containing (Ag content of about 6.8–8.2 wt %) polymer complexes based on the synthetic homopolymer of 1-vinyl-1,2,4-triazole and its copolymers have been synthesized and characterized. Structural features of macromolecular complexes were studied by magnetic resonance techniques (EPR, NMR) and other analytical methods (FTIR, SEM, UV– vis , atomic absorption analysis, etc.). The spatial structure of the polymer chain fragment and silver ion/1-vinyl-1,2,4-triazole complexes were investigated by quantum-chemical calculations. The formation of coordinatively saturated polymer complexes of Ag(I) and highly oxidized forms of Ag(II) silver was analyzed. The sites of ions localization and reduced metallic silver in the structure of the polymer matrix were determined.
