The polymerization of N-vinylcarbazole in the presence of FeCl3-impregnated montmorillonite resulted in the formation of a poly(N-vinylcarbazole)-montmorillonite composite. XRD analysis of the composite revealed no expansion for d(001) spacing, in sharp contrast to that for the same composite prepared in the absence of FeCl3. This indicated that the poly(N-vinylcarbazole) was not intercalated in the montmorillonite lamellae but was glued to it in the same way as was polypyrrole in colloidal silica, zirconia, or tin oxide nanocomposite systems. TEM analysis revealed the particle size of the composite to be in the range 30-40 nm. The de conductivity of the poly(N-vinylcarbazole)-montmorillonite composite was in the range (3-5) x 10(-5) S/cm depending upon the FeCl3 loading of montmorillonite.
