Özet

Polyaniline-MnFe2O4-CTAB nanocomposite was successfully synthesized by using 1-butyl-3-methyl-imidazolium trifluoromethane sulfonate (RTILs) as ionic liquid and Cetyl trimethylammonium bromide (CTAB) as surfactant via in-situ polymerization. The calculated average crystallite size, D XRD, of the product was 26±4 nm. Conductivity and permittivity properties of Polyaniline-MnFe2O4 nanocomposite was also exemplified by means of an impedance spectroscopy, which would be evaluated at frequency ranges up to 3 MHz for temperature range of 20-120 °C. In general, ac conductivity remains almost unchanged until it reaches up to 160 kHz, and then reduces slightly almost for all temperatures except for some slight fluctuation somehow at lower temperatures. The values fluctuate between 1.1-1.6 mS/cm at above all temperatures. © 2013 Springer Science+Business Media New York.
