摘要：

A conductive polypyrrole/montmorillonite (PPY/MMT) nanocomposite was synthesized by the in situ polymerization of polypyrrole in the gallery of montmorillonite layers. HCl was adopted as a dopant of the conductive PPY polymer. The PPY/MMT film was prepared by a spin-coating method from the colloidal solution of the PPY/MMT nanocomposite. Nanocomposites have been characterized by powder X-ray diffraction (XRD) and electrical dc resistivity measurements. XRD patterns showed that all samples of PPY/MMT layered nanocomposites contain an organic polymer between all individual MMT sheets. Although the electrical resistivity of the PPY polymer was highly dependent on the pH of the solution, the electrical resistivity of the PPY/MMT nanocomposite was almost independent of the pH of the solution.
