Summary, etc. <strong>The synthesis and characterization of polyaniline (PANI)/TiO<sub>2 </sub>polymer composites have been studied. The synthesis method is based on chemical oxidative polymerization of aniline added with various weight % of TiO<sub>2</sub> in the presence of ammonium persulphate as an oxidant. The results of XRD confirm the presence of TiO<sub>2</sub> in the composites. The FTIR shows systematic shifting of the characteristic bands of PANI with the increase in content of TiO<sub>2. </sub>The SEM images revealed uniform distribution of TiO<sub>2 </sub>particles in the PANI matrix. The evaluation of the dynamical parameters for PANI/TiO<sub>2 </sub>composites using technique such as TGA has been reported. The thermal stability of composites increases with the increase in TiO<sub>2 </sub>weight %. Although PANI/TiO<sub>2</sub> composites show lower <em>dc</em> electrical conductivity<em> </em>as compared to PANI and the conductivity decreases with increasing content of TiO<sub>2</sub>, but they show a higher thermal stability than that of<em> </em>PANI. Further, the <em>dc</em> electrical conductivity is observed to increase with the increase in temperature. This work opens new perspectives for the use of PANI/TiO<sub>2 </sub>composites as a conducting material at high temperatures.</strong>
