FIELD: chemistry.SUBSTANCE: method of obtaining films based on polyvinyl alcohol with nanostructured silver includes obtaining silver nanoparticles, their combination with polyvinyl alcohol and formation of film. Silver nanoparticles of required size are obtained by mixing water solutions of silver nitrate and L-cysteine in molar ratio 1.25-2.00. Combination of silver nanoparticles with polyvinyl alcohol is carried out in 10-12 wt % water solution of polyvinyl alcohol at temperature 85-90°C and volume ratio of mixed solutions 1:1 with obtaining supramolecular polymer. Obtained films can be applied in medicine, in particular in surgery for treatment of wounds, burns, injuries as minimal traumatic, biocompatible and biosoluble, antimicrobial bandages for injured skin.EFFECT: increased application efficiency.2 cl, 1 tbl, 3 dwg |
