In the present work, Polyaniline (PANI) and Polyaniline-Titanium dioxide (PANI-TiO 2 ) composite have been synthesized separately by chemical polymerization of aniline without/with TiO 2 . Characteristic absorption bands of PANI and TiO 2 in the composite were confirmed by FT-IR studies, indicating the interaction of PANI with TiO 2 . Comparative study of XRD patterns of PANI and the composite confirmed superficial deposition of PANI on TiO 2 and the average size of the composite particle was found to be 25 nm. The aggregated granular porous morphology of the composite was confirmed by its SEM image. The composite's sensing response to humidity at room temperature was tested and was found to be 84.21 % in the range 25 % -95 % RH. The response and recovery time of the composite at 95 % RH were measured to be 60s and 100s respectively and its sensing stability over a period of one month was also confirmed.

“…The preparation of PANI/TiO 2 , PANI/Cu, PANI/Au, PANI/Ag has been reported. [9][10][11][12][13][14][15][16][17][18] Conducting PANI supported PdNPs were synthesized by the reduction of Pd nitrate on the surface of PANI through electrochemical methods. [19] Amaya et al [20] reported on the template synthesis of CP/PdNPs composites.…”

We report the large scale preparation of nanostructured polyaniline‐Pd nanoparticles composites (designated as PANI(NS)‐PdNPs) through a “seed” induced bulk polymerization. Initially, a small quantity of PANI(NS)‐PdNPs was formed inside the cavities of MCM‐41 and used as the “seed” for the bulk preparation of PANI(NS)‐PdNPs composite. For a comparative purpose a PANI‐PdNPs composite was also prepared in the absence of the seed. FESEM image of PANI(NS)‐PdNPs composite (bulk) shows nanofibrillar morphology. Further, transmission electron microscopy reveals the presence of spherical Pd nanoparticles. PANI(NS)‐PdNPs composite (bulk) showed a good catalytic activity towards reduction of 4‐nitrophenol.magnified image

“…While it is worthy to note that polyaniline-TiO 2 nanocomposites have been synthesized and characterized [78][79][80][81][82][83], it should, however, be emphasized that these nanocomposites are not intercalated, but rather consist of TiO 2 nanoparticles, in either the anatase or rutile phase, mixed with the polymer.…”
