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.

A single precursor - K2SeS2O6 was used as both sulfur and selenium source.  In aq. soln., SeS2O2-6 diffused into the polymer where it reacted with Cd2+ ions to form cadmium chalcogenide particles.  Crystallinity of the composite material was analyzed via XRD and both CdSe and CdS were detected within the material at all deposition conditions of temp. and SeS2O2-6 - chalcogenization - exposure time.  A complex surface speciation was obtained using XPS anal.  Formation of the protonated amide species was obsd. in combination with the adsorbed SO2-4 on the surface of the polymer confirming that SeS2O2-6 and its decompn. products hydrolyzed to form cadmium chalcogenides and H2SO4.  A significant red shift in UV-vis spectrum was obsd. with the increasing chalcogenization time of PA, whereas Cd2+ soln. temp. had very little effect on the apparent thickness and the optical properties of the composite materials.  SEM surface anal. revealed sub-micron particles deposited on top of the PA-CdSe-CdS composite materials in continuous overlapping films, showing a possible dual crystal growth mechanism.

These were deposited using a K2SeS2O6 precursor soln. at 60 °C followed by cadmium acetate (Cd(CH3COO)2).  An aq. AgNO3 soln. was used as the Ag source.  XRD patterns showed a complex PA-Cd-S-Se-Ag film cryst. compn. with CdS, CdSe, Ag2S and Ag2Se peaks.  Calcd. dislocation d. ranged within 5-15 × 1013 lines·m-2 indicating high quality at. layers.  Atomic Absorption Spectroscopy (AAS) showed five- to ten-fold excess of chalcogens to metals in the thin films formed.  No chalcogenides were obsd. on the sample surface during XPS anal. after Ag exchange due to the desorption of CdS and CdSe layers, not diffused into the bulk of the polymer suggesting that silver chalcogenides were located subsurface, as opposed to the outermost layer, likely comprised of Ag2O.
