The use of low molecular weight biocides for the treatment of premises with high sanitary standards has significant disadvantages associated with the durability of such coatings, as well as the increasing resistance of bacteria. Biocidal compositions based on interpolyelectrolyte complexes (IPEC) are of potential interest for practical use, since they contain regions with free charged cationic groups that can provide both a biocidal effect and adhesion to hydrophilic surfaces. Also, the hydrophobic regions of IPEC can improve adhesion to hydrophobic surfaces, as well as modify such systems with low molecular weight bioactive compounds, for example, silver oxide Ag2O, which has widely proven itself as a biocide. Such a system will have increased durability along with a dual biocidal action. The decisive advantages of such ternary systems are increased wear resistance along with a dual biocidal action. In this work, we studied the formation and properties of water-soluble IPECs based on pH-independent polydiallyldimethylammonium chloride (PDADMAC), whose biocidal properties are widely known, and sodium polystyrenesulfonate (PSS). IPEC was also modified by incorporating Ag2O nanoparticles to obtain a ternary composite PDADMAC/PSS/Ag2O.
