Structure characterization of polystyrene-molybdenum bisulfide intercalation materials prepared by one-step and its oxidation behavior investigation

Polystyrene/molybdenum disulfide (PS/MoS₂) nanocomposites were prepared by means of one-step in situ anion polymerization of the intercalated monomers. The nanocomposites were characterized by means of XRD, FT-IR and SEM. The results indicate that the interlayer of MoS₂ has been expanded 0.672 nm by intercalating polystyrene molecules, it shows the nanocomposites are 'intercalation' composites. The oxidation behavior of the intercalation composites prepared by one-step and two-step method were investigated by XPS. The results indicate that the oxidation behavior of the two intercalation composites is different from each other, the former is mainly resulted in 'Mo⁴⁺' to 'Mo⁶⁺', the later is mainly resulted in 'S^-2' to 'S⁶⁺' for MoS₂, respectively.
