“…First of all, it is explained by their unique optical, electronic, catalytic and other properties, which sharply distinguish them from their analogs -microscale objects. Therefore, the hybrid materials containing silver nanoparticles are perspective for development of catalytic systems and also for use in optoelectronics and nanophotonics 3,4 . Furthermore, nanocomposite materials with silver nanoparticles are widely applied as effective antibacterial and antiviral medicines [5][6][7][8][9][10] .…”

The objective of this work is to study the peculiarities of structural organization, morphology, thermomechanical, electrical and antimicrobial properties of nanocomposites based on pectinpolyethyleneimine interpolyelectrolyte complexes and silver nanoparticles in dependence on the type of reducing agent being applied for chemical reduction of silver ions in the interpolyelectrolyte-metal complexes. The average size of Ag nanoparticles is shown to be increased with decreasing of the activity of reducing agent (E 0 ) and equals to 3.8 nm, 4.3 nm, and 15.8 nm, respectively, when engaging sodium borohydride (-1.24 V), hydrazine (-1.15 V) and ascorbic acid (-0.35 V). Moreover, it was found that the crystallite size of Ag nanoparticles also had the smallest value for nanocomposites obtained involving NaBH 4 as reducing agent. Ag-containing nanocomposites prepared by reduction of silver ions in interpolyelectrolyte-metal complexes while applying a range of reducing agents are characterized by different electrical properties and polymer matrix' glass transition temperature. The influence of silver nanoparticles' size incorporated in the polymer matrix on the antimicrobial activity of nanocomposites has been established. The inhibition zone diameter of Staphylococcus aureus and Escherichia coli was higher for nanocomposites obtained using sodium borohydride and hydrazine compared to nanocomposites where ascorbic acid was used as the reducing agent.

“…Obtaining organic-inorganic nanocomposites based on functional polymers appears to be a promising direction. In the processes of nanoparticle formation, a stabilising matrix is necessary, since the presence of various functional groups allows further modification [1][2][3], opening up promising new avenues for utilising target composites [4][5][6].…”

A light scattering study was performed on new silver-containing polymer nanocomposites based on water-soluble copolymers of 1-vinyl-1,2,4-triazole having sodium salt of vinylsulphonic acid of various compositions. The formation of nanocomposites was carried out using chemical reduction of silver ions by sodium borohydride in a copolymer-containing aqueous medium. According to the dynamic light scattering data, a decrease in the average sizes of metal-polymer coils in water-salt solutions of nanocomposites is explained in terms of an increase in the content of sulphonate groups in the stabilising polymer matrix. The electrophoretic light scattering with phase analysis of synthesised nanocomposites reveals the zeta potential (ζ) to vary from-35.0 to-75.3 mV with an increased sulphonate unit proportion in the stabilising polymer matrix, indicating an increase in the stability of the colloidal system. The functional composition of the stabilising polymer matrix is established to provide a significant effect on the hydrodynamic dimensions of polymer nanocomposites in an aqueous medium.
