In this work the nanocomposites of poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) host matrix with porous silicon and ZnO nanoparticles were manufactured. The charge transport and relaxation processes in organic-inorganic nanocomposites were analyzed based on complex studies of electrical conductivity and depolarization current in the wide temperature range. By means of impedance spectroscopy we have established that increase of content of ZnO nanoparticles causes the rise in the internal resistance of the hybrid films. Based on the spectra of thermally stimulated depolarization current the localized electron states in the experimental samples are found. The combination of the porous silicon and zinc oxide nanoparticles provides an increase of surface area of the sensors and their high sensitivity to water molecules.
