| Abstract [eng] |
The layers containing cadmium selenide, CdxSe, were formed on the surface of semi hydrophilic polymer – polyamide 6 (PA) for the first time by sorption-diffusion method using acidified solution of potassium selenotrithionate, K2SeS2O6, as a precursor of selenium. The concentration of sorbed selenium increases with the increase of the duration of PA treatment in K2SeS2O6 solution. The cadmium selenide containing layers form on the surface of PA after the treatment of seleniumized polymer with cadmium acetate, Cd(CH3COO)2·2H2O, solution: the anions SeS2O62– containing selenium atoms of low oxidation state react with the cadmium(II) ions. The conditions of a polymer initial seleniumization and of seleniumized PA treatment with cadmium acetate solution determine the concentration of cadmium and the composition of chalcogenide layer. The concentration of cadmium in the chalcogenide layer increases with the increase of initial chalcogenization duration only up to about 2 h and the temperature of selenotrithionate solution. XRD confirmed the formation of cadmium selenide containing layers on the surface of PA. The results of XPS and XRD patterns study of not earlier studied CdSe containing layers on PA showed their phase composition of two cadmium selenide phases – zinc blende (cubic) CdSe, wurtzite (hexagonal) CdSe, cadmium(II) oxide, CdO, and cadmium(II) hydroxide, Cd(OH)2. Accordingly data of XRD and XPS analysis the composition of CdSe containing layers depends on the conditions of these layers formation. The data determined enable formation of the layers containing cadmium selenide on the surface of PA by the sorption-diffusion method using the solution of potassium selenotrithionate as a precursor of selenium. |
