Development of new biocidal nanocomposite materials for protecting underwater structures from biofouling
https://doi.org/10.22349/1994-6716-2025-121-1-59-70
Abstract
The NRC “Kurchatov Institute” is working on the creation of antimicrobial nanocomposites containing biogenic colloidal nanosilver (NPsAg). Biogenic NPsAg obtained by microbial synthesis using bacterial cells and AgNO3 solution in liquid and dry preparative forms. To protect underwater objects from biofouling, a composition has been developed that includes complex chelated compounds of transition metals Cu, Zn and biogenic NPsAg. Cu and Zn chelates are synthesized by a complexation reaction, the antimicrobial activity of which increases with the introduction of NPsAg. It has been established that NPsAg keep stability and biocidal effect during prolonged exposure to seawater, which is important for their utilization as part of antifouling coatings. The technology of introducing biocidal NPsAg into the composition of polymer nonwovens and ion exchange resins of various types has been developed.
