| titleOfInvention | SANITARY TYPE OF COMPOSITE NANOSTRUCTURES - ANTIMICROBIAL METAL OXIDE AND PROCESS FOR THE OBTAINING THEM |
| abstract | The invention relates to a composite material having an antimicrobial activity and to a process for its preparation. The material according to the invention consists of silver nanoparticles deposited on an oxide substrate and dispersed as aqueous colloidal suspensions with a gravimetric content of MeO of 2 ... 10% and Ag of at least 0.1%, based on the mass of the suspension, and not more than 5%, based on MeO, containing, as dispersing and stabilizing agents, substances with antimicrobial properties. According to the invention, the process consists in dispersing TiO2 or ZnO nanopowders for 3 ... 10 min by sonication in a 0.75 ... 1.5% aqueous solution of sodium polyacrylate or sodium dodecyl sulfate, which adds a protective agent up to a concentration of 5 to 10 g / l, with stirring at 1200 ... 1500 rpm and heating at a temperature of 70 ... 80 ° C, and an aqueous solution of AgNO2 ... 40 mM, with stirring and heating for 1-2 hours, then the suspension is rapidly cooled to 4 ° C, maintained for 12 to 15 hours in the dark, a 0.05 solution is added. .0.5% NaHB in a 1: 1 to 1: 1 ratio of 1: 1 AgNO: NaBH, after which the product is decanted, centrifuged, washed and dried. |
