AB  - We report on self-assembly of polymer and molybdenum oxide chains into a new 
      class of lamellar hybrid materials. Aqueous ammonium molybdate and polyvinyl 
      alcohol (PVA) or carboxymethyl cellulose (CMC) were used as the starting 
      materials. Ammonium molybdate was hydrolyzed into layered molybdenum oxide under 
      acidified conditions. The organic polymer chains and the inorganic molybdenum 
      oxide layers self-assemble and pack into new hybrid composites. Scanning electron 
      microscope (SEM) images and polarized microscopy show that these two new 
      materials have typical lamellar structure. Transmission electron microscope (TEM) 
      images show that the layer thickness is about 100 nm. X-ray diffraction (XRD) 
      data confirm the formation of inorganic molybdenum oxide. Differential scanning 
      calorimetry (DSC) and thermogravimetric analysis (TGA) data gave thermal behavior 
      of these composites. The mechanism of this hybrid reaction and the templating 
      function of polymers were discussed in this paper. A special entropy effect was 
      discovered when polymer was used as guest species. This entropy effect makes 
      polymers preferential candidates as guest species rather than small molecules 
      when fabricating organic/inorganic layered hybrid materials. We believe that this 
      opens a new way to create organic/inorganic hybrid superstructures.
