Abstract
The conducting polypyrrole–montmorillonite clay (Ppy–MMT) composites were prepared by chemical polymerization. The prepared composites were subjected to structural, thermal and morphological characterizations and dc conductivity measurement. The dc conductivity of Ppy–MMT composites measured at room temperature was found to decrease from 2.25 to 0.31 S/cm with an increase in the percentage of montmorillonite (MMT) from 1% to 7%. The surface morphology of the prepared composites is denser and more compact compared to pure montmorillonite as can be evidenced from SEM micrographs. The formation of Ppy–MMT composites was supported by Fourier transform infrared (FTIR) spectra of the composites.
