Description	Journal: Iop Conference Series: Materials Science and Engineering We produced nanocomposites comprised of polyazomethine and reduced graphene oxide by solution mixing. The nanofiller concentration ranged from 0.25 to 1.5 wt.%. Both neat polymer and nanocomposites samples were investigated using broadband dielectric spectrometry under the same conditions. The electrical conductivity σ of the samples was examined as a complex value being a combination of two parameters: dc conductivity $(σ_{dc}$ ) and ac conductivity $(σ_{ac}$ ). The temperature dependences of $σ_{ac}$ were found to follow the Arrhenius equation, whereas the frequency dependences of $σ_{ac}$ were shown to obey a power law. We proposed that the correlated barrier hopping could explain behaviour of $σ_{ac}$ of the nanocomposites under study.
