APPLYING THE POLYVINYLPYRROLIDONE AS A HIGHLY EFFICIENT REDUCTANT AND STABILIZER IN REACTIONS OF SILVER NANOPARTICLES SYNTHESIS

The regularities of silver nanoparticles derivation using polyvinylpyrrolidone as a reducing agent and stabilizer simultaneously have been studied. The silver spherical nanoparticles was confirmed by UV, FT-IR spectroscopy and TEM analysis. The influence of temperature and reagent concentration on the kinetics of silver reduction from argentum salts was determined. Silver-containing composites based on copolymers of polyvinylpyrrolidone and methacrylic esters with silver nanoparticles in the form of porous blocks and films were synthesized. Also their high bactericidal and fungicidal properties were revealed. The developed porous composites are recommended for application in medicine to replace damaged bone tissue in the processes of osteogenesis.
