The lithiation and subsequent hydration of MoS{sub 2} provides an exfoliated, collodial suspension which may incorporate molecular clusters or organics upon restacking. The paper reports here the preparation of polyether - disulfide nanocomposites by the interaction of colloidal MoS{sub 2} with an aqueous or organic solution containing the appropriate polymer. MoS{sub 2} was exfoliated by the method indicated above. The interaction of the resulting colloidal suspension with solutions containing either poly(ethylene oxide) or methoxy-linked polyethylene glycol results in the formation of nanocomposites with polymer incorporated within the disulfide galleries. X-ray diffraction indicates an expansion of up to 8.3 {angstrom} between MoS{sub 2} sheets (c = 14.5 {angstrom}) consistent with the incorporation of polymer bilayers within the galleries. Structural data are presented for a range of polymer - disulfide stoichiometries.
