Synthesis and Characterization of Intercalate Phases in the Organic–Inorganic Polyaniline/V2O5 System

The synthesis, and spectroscopic and structural characterization of a series of hybrid PAni/V2O5 materials are reported. We have performed a systematic study of the synthesis of the hybrids by direct in situ reaction of aniline with V2O5 hydrogels and have determined key parameters for the reproducibility of the materials obtained. We have established the existence of two phases in the PAni/V2O5 system corresponding to the intercalation of one and two monolayers of PAni into V2O5. The characterization of these materials includes FTIR spectroscopy, X-ray diffraction, Thermogravimetric analyses, and resistivity measurements.
