Synthesis of Silver and Gold Nanoparticles in Sodium Alginate Matrix Enriched with Graphene Oxide and Investigation of Properties of the Obtained Thin Films

Polymer nanocomposites containing nanometals became a subject of interest due to their bactericidal properties. Different polysaccharides have been used as matrices for nanosilver and nanogold synthesis. In this study, we present novel, environmentally friendly method the preparation sodium alginate/nanosilver/graphene oxide (GOX) alginate/nanogold/graphene GOX characteristics. The formation approximately 10–20 nm ball-shaped Ag Au nanoparticles was confirmed by UV–vis spectroscopy, scanning electron microscopy (SEM) Fourier transform infrared (FTIR) spectra. incorporation sheets within ALG matrix improved thermal stability film, which measured using differential calorimetry (DSC). We also estimated molecular weights polysaccharide chains with size exclusion chromatography coupled multiangle laser light scattering refractometric detectors (HPSEC-MALLS-RI). composites were more prone enzymatic hydrolysis. strongest bacteriostatic activity observed sample nanosilver.
