AbstractThe electrical conductivities of a series of MoS2‐organic layer nanocomposites prepared by the intercalation of donors like poly(ethylene oxide) and secondary amines are compared. Although for intercalated MoS2 species a metallic behavior is expected, the products behave as semiconductors probably because of their layered nature. Observed conductivities at room temperature depend on the host‐guest charge transfer reflected in both the amount of residual lithium and the donor intercalation degree, as well as on the nature of the donor.
