| description | <p>The layers containing cadmium selenide, CdxSe,were formed on the surface of semihydrophilic polymer – polyamide 6 (PA) using acidified 0.10 mol/dm3 solution of potassium selenotrithionate, K2SeS2O6,as precursor of selenium. The concentration of sorbed selenium (at 60 oC) increases with the increase of the duration of PA treatment in K2SeS2O6solution. The cadmium selenide containing layers are formed on the surface of PA after the treatment of seleniumized polymer with cadmium acetate, (Cd(CH3COO)2·2H2O, solution (60–80 oC):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. The results of XPS and XRD confirmed the formation of cadmium selenide layers on the surface of PA. XRD patterns study of not earlier studied CdSe layers on PA showed their phase composition of two cadmium selenides phases – Zinc blende (cubic) CdSe,wurtzite (hexagonal) CdSe and cadmium(II) hydroxide, Cd(OH)2. Accordingly data of XRD and XPS analysis the macrostructure and composition ofCuSe layers depends on the conditions of these layers formation. The data determined enable formation of the layers of cadmium selenide on the surface of PA by thesorption-diffusion method using the solution of potassium selenotrithionate as a precursor of selenium.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.21.1.5097">http://dx.doi.org/10.5755/j01.ms.21.1.5097</a></p> |
