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.
