Abstract: The absorption spectra in the visible region and current-voltage characteristics in a wide range of electric fields have been investigated at the macroscopic level (planar structures) and at the microscopic level (using a conductive atomic force microscope) in films based on the electroactive polymer PEDOT: PSS and gold/silver nanoparticles (PEDOT: PSS + Au/AgNP). It has been shown that the behavior of the current-voltage characteristics of the nanocomposite films depends significantly on the electric field strength. It has been found that the introduction of gold nanoparticles into PEDOT: PSS in weak electric fields leads to an increase in the bulk conductance by almost two orders of magnitude (due to donor-acceptor interactions), a 50
