This paper describes the specific electric conductivity of thin films of the polymer polyaniline, depending on the type of material that is used for doping the specified polymer. In our own laboratory, there were made four series of doped samples of polyaniline thin films of which two series were doped with sulfuric acid (PANI-H2SO4), and the other two were doped with hydrochloric acid (PANI-HCl). It is also significant that two series of the mentioned samples of thin films were obtained at room temperature (20°C), and the other two at 0°C. Next, the analysis of the specific electrical conductivity of all series was performed in order to demonstrate that the material that reaches the thin film affects its electrical conductivity
