Modification of polyester and cellulose fiber-based materials with biologically active mono- and bimetallic nanoparticles

Resumo

A method was proposed for modification of cellulose and polyester textile materials with monoand heterometallic copper and/or silver sols for imparting the ability to affect microorganisms to textile matrices. Data were presented on the dynamics and features of the reduction of copper and silver cations in the presence of phosphonic acid derivatives and/or natural macromolecular compounds as chelators. The stable monometallic and mixed particles synthesized were shown to be effective in imparting antimicrobial activity to natural and synthetic fibers (through the example of Candida albicans fungus) and in protecting them against biodegradation by soil microflora and natural complex microflora.
