It has been shown that the surface morphology of the initial MNP-free polymer is absolutely smooth, but it dramatically changes after the kinetic loading of Ag on the polymer and then IMS of Ag-MNPs. These morphological changes can be explained by the interaction of Ag-NPs with the polymer chains, leading to a sort of additional cross-linking of the polymer. As a result, the modification of the gel-type matrix with Ag-MNPs leads to the increase of the matrix cross-linking, which results in the increase of its surface area and the appearance of nanoporosity in the polymer gel. Ag-MNPs are located near the polymer surface and do not form any visible agglomerations. All these features of the nanocomposites obtained are important for their practical applications in catalysis, sensor applications, and bactericide water treatmen cc-by (c) Bastos-Arrieta, Julio et al., 2013 https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Nanopartícules Ions metàl·lics Argent Nanoparticles Metal ions Silver Morphological changes of gel-type functional polymers after intermatrix synthesis of polymer stabilized silver nanoparticles info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
