“…The additives of ethanol were used for experiments (Reaction (8); (E 0 CH3˙CHOH −1.4 B [ 18 , 35 ]). The oxidation of alcohol radicals results in the formation of acetaldehyde, which acts as a weak reducing agent [ 18 , 31 , 36 ].…”

“…In recent years, great efforts have been invested in the development of one-stage methods for the production of nanocomposites, in which the synthesis of metal nanoparticles or metal oxides and the formation of a stabilizing matrix occurs in one reactor [ 1 , 2 , 3 , 4 , 5 , 6 , 9 , 10 , 11 , 12 ]. Radiation–chemical approaches are widely employed for the synthesis and modification of advanced polymer materials [ 6 , 13 , 14 , 15 , 16 , 17 , 18 ]. The possibility to change the radiation parameters such as dose rate and total absorbed dose over a wide range ensures unique opportunities for obtaining materials with tuned properties.…”

“…The possibility to change the radiation parameters such as dose rate and total absorbed dose over a wide range ensures unique opportunities for obtaining materials with tuned properties. Radiation-induced reduction results in the assembly of nanoparticles of a controlled size without impurities [ 6 , 15 , 16 , 18 ], which is especially important for medical and catalytic purposes. Radiation-initiated polymerization permits the obtaining of materials without residues of initiators or catalysts and makes it possible to carry out reactions without heating [ 13 , 17 ].…”

“…Nanocomposites also show thermo-responsive antibacterial properties [ 21 , 22 ]. The nanocomposites containing silver nanoparticles are prospective materials for optical and catalytic systems [ 1 , 15 , 16 , 18 , 23 ]. However, research attention was mainly paid to the production of biocidal materials, since the application of metal–polymer nanocomposites (unlike antibiotics) did not lead to bacterial resistance [ 24 , 25 , 26 ].…”

“…Thus, it is relevant to use eco-friendly and one-stage methods using radiation–chemical approaches for the synthesis of metal–polymer composites. Earlier, we successfully employed X-ray radiation for the preparation of film and soluble metal–polymer nanocomposites [ 12 , 18 , 31 , 32 ]. The possibility of obtaining hybrid materials in irradiated 0.1 wt.% aqueous solutions of 1-vinyl-1,2,4-triazole (VT) containing gold ions [ 12 ] was previously demonstrated using UV-visible spectroscopy.…”

Metal–polymer nanocomposite polyvinyltriazole–silver nanoparticles were obtained using one-pot synthesis in irradiated aqueous solutions of 1-vinyl-1,2,4-triazole (VT) and silver ions. Gel permeation chromatography data show that upon radiation initiation, the molecular weight of poly(1-vinyl-1,2,4-triazole) increases with increasing monomer concentration. To study the kinetics of polymerization and the features of the radiation–chemical formation of nanoparticles, UV-Vis spectroscopy was used. TEM images show a relatively small average size of the forming nanoparticles (2–3 nm) and a narrow size distribution, which shows the effective stabilization of nanoparticles by triazole substituents at a molar ratio of VT and silver ions of 25/1. The addition of ethyl alcohol was used to increase the efficiency of synthesis and suppress the crosslinking of macromolecules in solution. The results of the work show that aqueous–alcoholic solutions of 1 wt.% VT can be used to obtain soluble nanocomposite materials. 10 wt.% monomer solutions have prospects for use in the preparation of polymer gels filled with nanoparticles.

Poly‐1‐vinyl‐1,2,4‐triazole (PVT)‐based materials with silver nanoparticles are promising antibacterial products. The metal nanoparticles with controllable sizes were obtained by radiation‐induced reduction of the dispersions of complexes of PVT with silver ions. Formation of the silver nanoparticles in aqueous suspensions irradiated at pH 6.0, 2.5, and 2.0 was studied using methods of UV–VIS spectroscopy and transmission electron microscopy. UV–VIS spectroscopy has detected a change in the efficiency of interaction between protonated or non‐protonated PVT units and the surface of silver nanoparticles. The interaction of macromolecules with the metal surface under different degrees of protonation of PVT functional groups afforded the nanoparticles with a narrow size distribution and an average size from 3 to 10 nm. An increase in the acidity also leads to a decrease in the ratio of the generation/growth of nanoparticles. The radiation approaches both provide the synthesis of the nanoparticles of controlled sizes and permits to obtain the nanocomposites containing no impurities of chemical reducing agents. The nanocomposites obtained exhibit high antibacterial activity against various bacterial strains, which depends on the size of silver nanoparticles.

The immobilization of N,N‐diallyl‐N,N‐dimethylammonium chloride (DADMAC) on low‐density polyethylene (LDPE) films was carried out by the method of postradiation grafting using x‐ray radiation. The introduction of polycation exchanger links provided the appearance of hydrophilicity of the surface of the modified film. By measuring the wetting contact angle, IR and SEM, the island‐type character of the coating from grafted polyDADMAC was detected. The death of Gram‐negative bacteria Pseudomonas aeruginosa, Gram‐positive bacteria Staphylococcus aureus, and yeast (eukaryotes) Yarrowia lipolytica on the surface of the film with grafted polyDADMAC was demonstrated.
