Abstract

A novel electrically conductive Polyaniline-titanium(IV)sulphosalicylophosphate (Pani-TSP) cation exchange nanocomposite has been synthesized by in-situ chemical oxidative polymerization of aniline in the presence of Titanium(IV)sulphosalicylophosphate (TSP) nanoparticles. Pani-TSP was characterized by various instrumentation techniques like FTIR, FE-SEM, XRD, TGA, DTA, DTG and EDX. Characterization results confirms that synthesis of Pani-TSP was successfully achieved. Pani-TSP shows good ion-exchange capacity (IEC) (2.15 meqg−1) as well as electrical conductivity (1.531 S/cm) and isothermal stability in terms of DC electrical conductivity retention under ambient condition up to 110 °C. Pani-TSP cation exchange nanocomposite based sensor was fabricated for the detection of methylamine and ethylamine vapours at room temperature. Sensing performance of nanocomposite was checked over the concentration range from 0.1 M (vapour concentration 3.20%) to 0.7 M (vapour concentration 4.65%) aqueous amine. The rate of reaction of amines vapour sensing on Pani-TSP was determined as first order for methylamine and ethylamine vapours which suggest that rate of change in resistivity response is mainly due to amine vapours.
