Regularities of Obtaining Silver Nanoparticles in the Presence of Polyvinylpyrrolidone and Their Application for Osteoplastic Composites

The regularities of obtaining silver nanoparticles in the presence polyvinylpyrrolidone, which was both a reductant and stabilizer nanoparticle dispersion, have been studied. influence such factors as temperature, polyvinylpyrrolidone amount, concentration nature salts on shape size has established. chemistry reaction with formation vinylsuccinimide units structure macromolecules proposed, is confirmed by results IR spectroscopy. It established that are influenced salt nature. If nitrate used for reduction reaction, formed mainly form triangular prisms polyhedra. When using acetate, spherical predominantly formed. High-quality if mass ratio : more than 20. decrease this deteriorates stabilization increases particle until nanocrystals several hundred nanometers size. kinetics studied solution. found to occur faster increasing temperature amount. Silver provide fungibactericidal properties hydroxyapatite-filled osteoplastic porous composites based copolymers methacrylic esters.
