Polyaniline-MnFe2O4 nanocomposite was successfully synthesized by using 1-butyl-3-methyl-imidazolium bromide (BMIMBr) as ionic liquid and cetyl trimethylammonium bromide (CTAB) as surfactant via in-situ polymerization. Structural, morphological, spectral and magnetic investigation of the product were done by X-Ray powder Diffractometry (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Thermal Gravimetric Analyzer (TGA), Transmission Electron Microscopy (TEM), Vibrating Sample Magnetometry (VSM) respectively. Electrical Properties of PANI-MnFe2O4-CTAB nanocomposite was characterized with a measurement of an impedance spectroscopy, which was evaluated at frequency range varying from 1Hz to 3MHz for temperature range of 20 - 120oC. In general ac conductivity remained almost unchanged until it reaches up to 160 kHz, and then reduced slightly almost for all temperatures except for some slight fluctuation somehow.
