Inverted Emulsion Polymerization of Conducting Polyaniline-Titanium Dioxide Nanocomposites |
| 초록 |
Conducting polyaniline-TiO2 nanocomposites have been synthesized by the inverted emulsion polymerization method. Aqueous mixtures of aniline, a free-radical oxidant and/or TiO2 nanoparticles were utilized to synthesize the hybrid nanocomposites. The polymerization was carried out in a nonpolar solvent (chloroform) in the presence of a protonic acid (hydrochloric acid) as a dopant and an emulsifier (cetyl trimethylammonium bromide). SEM & TEM images represent the resultant PAni-TiO2 nanocomposites with the diameter range of 50-200 nm. Electrical conductivities were checked by standard four-point probes method and found to be 0.38 S/cm for bulk PAni and 0.11 S/cm for PAni-TiO2 nanocomposites. UV-visible absorption showed two electronic bands at about 320 and 596 nm for bulk PAni and the blue-shifted bands with the intensity changes due to the formation of PAni-TiO2 composites. TGA revealed that the composites have a higher degradation temperature than the PAni alone. |
