“…[9][10][11] The electronic, optical, photo-electrochemical, photoconductive, photovoltaic, thermal and sensing, for example, gas sensing and biosensing, properties of PANI could be improved by incorporating PANI with polystyrene latex, multiwalled carbon nanotubes, single-walled nanotubes, montmorillonite, graphite, MCM-41, TiO 2 and SnO 2 micro and nanoparticles. [9][10][11][12][13][14][15][16][17][18] PANI composites have also been shown to possess a variety of unique mechanical, electrical and structural properties because of synergistic effect from intimate mixing between PANI and inorganic or organic components at a molecular and an atomic level.…”

Recently, polymer matrix-based nanocomposites have become a prominent area of research and development in optics, as well as in optoelectronic, biomedical, electrical and electronic applications. Organic polymer-based electronic devices have the potential to be lower in cost and more flexible in the manner in which they are manufactured. However, they need significant improvement in both efficiency and long-term stability. Therefore, we made an attempt to synthesize zinc oxide (ZnO)-polyaniline (PANI) using chemical and emulsion polymerization techniques. The properties of ZnO-PANI films were then systematically characterized with several physical techniques. Electrochemical investigations revealed that the individual redox properties of ZnO and PANI can be maintained in a nanocomposite ZnO-PANI system. Furthermore, our results indicated that ZnO-PANI films can exhibit a wide redox potential window. Moreover, we observed the formation of a single-layer nano-Schottky junction in ZnO-PANI films, and interesting positive temperature coefficient properties in ZnO-PANI-embedded polystyrene films. Polymer Journal ( INTRODUCTIONIn recent years, there has been considerable interest among researchers to develop novel inorganic _ organic hybrid materials with compositions modulated on the nanoscale because of their many potential applications in display technologies, microelectronics, catalysis, sensors and molecular electronics. 1 The fabrication of nanocomposite films by wet chemical techniques has been proven to be a more simple and inexpensive strategy than technologically demanding physical methods. 2 Recently, Ram et al. [3][4][5][6][7][8] developed metal oxide and conducting polymer nanocomposite films of TiO 2 -PANI, TiO 2 -polypyrrole, SnO 2 -polyhexylthiophene, TiO 2 -poly (thiopheneaniline) nanocomposite, Mn-Ferrite-PANI and MWCNT-poly (o-anisidine) using wet chemical methods and used them extensively in gas sensing and molecular electronics applications. PANI is one of the most widely studied materials because of its unique electrochemical, chemical and physical properties. In addition, PANI exhibits high electrical conductivity and good environmental stability in both doped and pristine (undoped) states. 9-11 The electronic, optical, photo-electrochemical, photoconductive, photovoltaic, thermal and sensing, for example, gas sensing and biosensing, properties of PANI could be improved by incorporating PANI with polystyrene latex, multiwalled carbon nanotubes, single-walled nanotubes, montmorillonite, graphite, MCM-41, TiO 2 and SnO 2 micro and nanoparticles. 9-18 PANI composites have also been shown to possess a variety of unique mechanical, electrical and structural properties because of synergistic effect from intimate mixing

“…However the refractive index of the film composed of TiO 2 nanoparticles and polyelectrolytes is significantly decreased because of the presence of pores and polyelectrolyte with low refractive index relatively [20]. On the other hand, although the TiO 2 thin film comprising polyelectrolyte and TALH solution which is stable and double negatively charged inorganic precursor [21] shows high refractive index (n = 1.68¨1.8), this film has a small film growth with the average thickness (ca.1.5¨5 nm) of a bilayer [22,23].…”
