Tolstov, I. Bey, V. Matyushov] The spectral characteristics of the complex of Ag(I) with biuret and its conversion into a dispersion of silver nanoparticles (SN) were investigated. Nanocomposites based on biuret-containing polyurethane and SN were obtained. Analysis of their IR spectra established the nature of the interaction between the SN and the polymeric matrix and also the effect of the nanofiller on the hydrogen bonds between the components of the polymeric component. Investigation of the sorption characteristics of the nanocomposites showed that their lyophilicity is determined both by the presence of the SN, acting as sites for physical cross-linking, and by the presence of highly hydrophilic products formed during the formation of the SN.
