A novel conductivity composite from polyaniline (PANI) and layered zirconium phenylphosphonate (ZrPP) was carried out through in situ chemical oxidation polymerization by the addition of an appropriate amount of ammonium peroxodisulfate solution, and the relevant structure and properties were investigated. The composites were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. The electrical conductivity was measured by the four-probe technique. The electrical conductivity of the composites improved with increasing ZrPP loading, and the materials had reasonably good electrical properties, even with 40 wt % loadings of ZrPP in the polymer matrix. The results reveal that π–π interaction was formed in the composites, which enhanced the electrical conductivity of the composites compared to that in neat PANI. © 2010 Wiley Periodicals, Inc.
