Tuning the size and spatial distribution of metal nanoparticles is a key issue for obtaining metal–polymer nanocomposites with desirable properties. It was shown that action white X-ray radiation (bremsstrahlung, Emax ∼ 30 keV) on swollen films interpolyelectrolyte complexes copper silver ions in an aqueous—alcoholic environment resulted formation specific type nanostructures characterized by transmission electron microscopy (TEM). The structure pattern explained autocatalytic enhancement...
Due to the presence of cationic units interpolyelectrolyte complexes (IPECs) can be used as a universal basis for preparation biocidal coatings on different surfaces. Metallopolymer nanocomposites were successfully synthesized in irradiated solutions polyacrylic acid (PAA) and polyethylenimine (PEI), dispersions non-stoichiometric IPECs PAA-PEI containing silver ions. The data from turbidimetric titration dynamic light scattering showed that pH 6 is optimal value obtaining IPECs. Metal...
In order to control pathogenic microorganisms, three polymer compositions were prepared and tested. First, a water-soluble positively charged polycomplex was synthesized via the electrostatic binding of anionic polyacrylic acid an excess polyethylenimine enhance biocidal activity polycation. Second, aqueous solution AgNO3 added polycomplex, thus forming ternary polycation-polyanion-Ag1+ complex with additional antimicrobial effect. Third, resulting subjected UV irradiation, which ensured...
Gold nanoparticles (AuNPs) with average sizes of 1.5 nm and 3 narrow size distribution have been prepared in the irradiated aqueous solutions suspensions Au(III)-complexes units poly(1-vinyl-1,2,4-triazole) (PVT) – poly(acrylic acid) (PAA) respectively. The formation AuNPs has studied using UV-VIS spectroscopy transmission electron microscopy. effective stabilization ultrasmall is achieved due to combination both electrostatic interaction polymer specific adsorption functional groups on...
Star-shaped poly(acrylic acid) macromolecules act as nanoreactors for the preparation of narrow-dispersed copper nanoparticles by radiation-induced reduction copper(<sc>ii</sc>) ions.
Abstract Poly‐1‐vinyl‐1,2,4‐triazole (PVT)‐based materials with silver nanoparticles are promising antibacterial products. The metal controllable sizes were obtained by radiation‐induced reduction of the dispersions complexes PVT ions. Formation in aqueous suspensions irradiated at pH 6.0, 2.5, and 2.0 was studied using methods UV–VIS spectroscopy transmission electron microscopy. has detected a change efficiency interaction between protonated or non‐protonated units surface nanoparticles....
Abstract The immobilization of N , ‐diallyl‐ ‐dimethylammonium chloride (DADMAC) on low‐density polyethylene (LDPE) films was carried out by the method postradiation grafting using x‐ray radiation. introduction polycation exchanger links provided appearance hydrophilicity surface modified film. By measuring wetting contact angle, IR and SEM, island‐type character coating from grafted polyDADMAC detected. death Gram‐negative bacteria Pseudomonas aeruginosa, Gram‐positive Staphylococcus aureus...
Self-confined synthesis of silver nanoparticles (AgNPs) within mesoporous host matrixes based on poly(ethylene terephthalate) (PET) upon X-ray radiolysis is studied.Mesostructured PET with a porosity 35 vol% and pore dimensions below 10 nm were prepared loaded Ag + ions via the mechanism environmental crazing.Upon subsequent irradiation silver-loaded samples, experience reduction into 0 mesopores.In this case, solvated electrons, alcohol radicals, acetaldehyde act as effective reducing...
