| Abstract | Composite org.-inorg. functional materials are of significant importance in various applications of science and technol. In this work, physicochem. characterization of such composite materials obtained after the exposure of polyamide PA 6 to K2SeS2O6 precursor soln. was performed. Chalcogenized polymer surface was characterized using X-ray diffraction, IR, and UV-vis spectroscopies while their bulk chem. anal. was performed using at. absorption spectroscopy. Crystallite size was not found to change with the exposure to K2SeS2O6 precursor but PA 6 chain-chain sepn. decreased. Importantly, IR and X-ray analyses showed chem. bonding taking place between the PA 6 and SeS2O2-6 ions via -NH- functional group. A distinct change in bandgap, Eg, value was obsd. in UV-vis spectra due to the presence of SeS2O2-6, SeSO2-3 and Se2S2O2-6 ions formed via decompn. of the precursor material in acidic medium. After extended 4 h halcogenation a distinct absorption due to the elemental selenium was also obsd. as obtained from Tauc plots. [on SciFinder(R)] |
