Utilizing the solvothermal synthesis technique, lithium intercalated tungsten disulfide Li x WS2 with x >1 was obtained, which was allowed to react with water to the formation of single-molecule-layer suspension of tungsten disulfide. The layered nanocomposites PEG, PEO/WS2, intercalating poly(ethylene glycol) (PEG, MW≈1×103, 6×103, 1×104) and poly(ethylene oxide) (PEO, MW≈3×105) into the tungsten disulfide host galleries, were prepared using the improved exfoliation–adsorption technique. It was revealed that the intercalated polymers within the host galleries are in a double-layer arrangement with an interlayer expansion of about 9Å. Despite high conductivity of the host material, those of the PEG, PEO/WS2 nanocomposites were found to be high in the order of 1×10−2 to 10−3 Scm−1 at ambient temperature, resulted from the guest–host charge transfers.
