Abstract

Copyright © Taylor & Francis Group, LLC. This communication reports the results obtained by the modification of gel-type ion exchange materials with functional metal nanoparticles having biocide activity. The modification is carried out by using Intermatrix Synthesis technique coupled with Donnan Exclusion Effect which results in the most favorable distribution of silver nanoparticles near the surface of the nanocomposite material. The surface of the polymer-metal nanocomposite is characterized by the worm-like structure due to the interaction of metal nanoparticles with polymer chains. This interaction leads to the appearance of nanoporosity in the matrix which enhances its mass-transfer characteristics. Moreover, it has been shown that modification of gel-type ion exchangers with silver nanoparticles essentially does not change the ion exchange properties of the initial polymeric matrix. Graphical Abstract: Intermatrix synthesis (IMS) of Ag functional metal nanoparticles (FMNPs) leads to a significant Surface modification of gel-type polymers without changing ion exchange properties of the polymeric support.
