“…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 ]. Thus, when ethanol is used as a scavenger of ˙OH radicals, only reducing products are generated in water–organic mixtures.…”

“…E 0 (Ag + /Ag 0 ) = −1.8 V [ 35 ], therefore, the reduction of silver ions to isolated atoms and the formation of small clusters (Reactions (15) and (16)) can be ensured by a hydrated electron [ 38 , 39 , 40 ]. The reduction of silver ions on the surface of nanoparticles, leading to the growth of nanoparticles (Reaction (17)), can occur due to reducing agents having lower reduction potentials, including acetaldehyde [ 18 , 31 , 36 ].…”

“…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.

“…Furthermore, polymer coatings are capable of destroying adsorbed bacteria, i.e., they exhibit biocidal properties [ 9 , 10 ]. In this case, macromolecules can serve as a matrix, in which a low molecular weight biocide or biocidal nanoparticles are distributed, they can also contain covalently attached biocidal molecules, and finally they may independently exert a biocidal effect due to their functional groups [ 11 , 12 , 13 , 14 , 15 ]. Among the polymers with biocidal properties, one should single out the class of polycations—synthetic or natural polyelectrolytes that carry a positive charge in the monomer unit [ 16 ].…”

Polymer coatings based on polycations represent a perspective class of protective antimicrobial coatings. Polydiallyldimethylammonium chloride (PDADMAC) and its water-soluble complexes with sodium polystyrenesulfonate (PSS) were studied by means of dynamic light-scattering, laser microelectrophoresis and turbidimetry. It was shown that addition of six mol.% of polyanion to polycation results in formation of interpolyelectrolyte complex (IPEC) that was stable towards phase separation in water-salt media with a concentration of salts (NaCl, CaCl2, Na2SO4, MgSO4) up to 0.5 M. Most of the polyelectrolyte coatings are made by layer-by-layer deposition. The utilization of water-soluble IPEC for the direct deposition on the surface was studied. The coatings from the PDADMAC and the PSS/PDADMAC complex were formed on the surfaces of hydrophilic glass and hydrophobic polyvinylchloride. It was found that formation IPEC allows one to increase the stability of the coating towards wash-off with water in comparison to individual PDADMAC coating on both types of substrates. The visualization of the coatings was performed by atomic force microscopy and scanning electron microscopy.

“…Polyelectrolytes have a highly important place among the polymers used for stabilizing dispersions of metal NPs [1,19,20,21]. In addition, these polymers may demonstrate antimicrobial, antitumor, anti-inflammatory and antioxidant properties and, thus, enhance the corresponding characteristics of silver NPs [5,22].…”

Stabilization of Silver Nanoparticles by Cationic Aminoethyl Methacrylate Copolymers in Aqueous Media—Effects of Component Ratios and Molar Masses of Copolymers

et al. 2019

The ability of aminoethyl methacrylate cationic copolymers to stabilize silver nanoparticles in water was investigated. Sodium borohydride (NaBH4) was employed as a reducing agent for the preparation of silver nanoparticles. The objects were studied by ultraviolet-visible (UV-vis) spectroscopy, dynamic light scattering (DLS), analytical ultracentrifugation (AUC) and scanning electron microscopy (SEM). Formation of nanoparticles in different conditions was investigated by varying ratios between components (silver salt, reducing agent and polymer) and molar masses of copolymers. As a result, we were successful in obtaining nanoparticles with a relatively narrow size distribution that were stable for more than six months. Consistent information on nanoparticle size was obtained. The holding capacity of the copolymer was studied.
