| description | A polyamide 6 films if treated with the potassium selenotrithionate, K<sub>2</sub>SeS<sub>2</sub>O<sub>6</sub>, solution in hydrochloric acid, absorbs selenium the form of selenotrithionate anion, SeS<sub>2</sub>O<sub>6</sub><sup>2-</sup>, and the anions decompose in polymer with time.<strong> </strong>Further interaction of selenized PA films with AgNO<sub>3</sub> solution (10 min, 80<sub> </sub>°C) leads to the formation of silver selenide layers on the polymer surface. The mechanism of formation of silver selenide layers on PA 6 films was proposed. The chemical analyzes show that the concentrations of silver and selenium in polyamide 6 film increase when increase the duration of polymer seleniumization. The molar ratio of Ag/Se in the layers of silver selenide on polyamide films varied from 0.57<sub> </sub>:<sub> </sub>1 to 0.7<sub> </sub>:<sub> </sub>1. The X-ray diffraction analysis confirmed the formation of silver selenide layers with elemental selenium in the surface of polyamide 6. The phases of orthorhombic naumannite - Ag<sub>2</sub>Se (24-1041) and monoclinic selenium - Se<sub>8</sub> (71-528) were identified in the formed layers.<p><a href="http://dx.doi.org/10.5755/j01.ms.17.4.775">http://dx.doi.org/10.5755/j01.ms.17.4.775</a></p> |
