Water-soluble polymer nanocomposites with silver nanoparticles

New water-soluble functional polymer nanocomposites with zero-valent metallic silver nanoparticles in the matrix of 1-vinyl-1,2,4-triazole and vinyl sulfonic acid sodium salt copolymer were synthesized. Nanocomposites with different silver contents (2,4-9,5%) were obtained by varying the ratio of copolymer and metal salt. The sizes of isolated nanoparticles are 2-14 nm and they are predominantly spherical in shape. Nanocomposites are well soluble in water and dipolar organic solvents and have thermal stability up to 250С. The obtained water-soluble silver-containing nanocomposites are promising for the development of biocompatible antiseptic materials for medical and biological purposes.
