Poly[oxymethylene-(oxyethylene)] has been inserted in the gallery space Of MoS2 by using the exfoliation/re-stacking properties of LiMoS2. The resulting intercalation compound shows enhanced electronic conductivity due to a structural transformation of the MoS2 framework. The material was also characterized by powder X-ray diffraction and thermogravimetric analysis. (C) 2003 Elsevier B.V. All rights reserved.
