Abstract

Electrically conductive polyaniline-titanium(IV)molybdophosphate (PANI-TMP) cation exchange nanocomposite was studied as sensing material for aliphatic alcohols (methanol, ethanol and 1-propanol) at room temperature. The nanocomposite was synthesized by sol-gel mixing of polyaniline (PANI) into inorganic precipitate of titanium(IV)molybdophosphate (TMP) and characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA) and ultraviolet-visible spectroscopy (UV-Vis). The composite showed good ion-exchange capacity, electrical conductivity and resistivity response towards alcohol vapours. It was observed that the sensor show good reversible response towards methanol vapours compared to ethanol and 1-propanol vapours. These studies suggest that the nanocomposite cation exchanger could be a good sensing material for methanol vapours at room temperature (25 °C).
