ABSTRACT
220The temperature dependences of optical absorption (transmittance) spectra of the conducting polymer films–polyaniline (PAn), poly-o-toluidine (PoT), poly-o-anisidine (PoA), poly-o-aminophenol (PoAPh) doped by sulfuric acid, potassium ferricyanide, and silver nanoparticles have been studied in the temperature interval T = 80–403 K. It has shown that temperature increasing causes a change in optical transmittance (absorption) spectra of polymers in all temperature range. However, characteristics of thermo-optical changes or thermochromic effects depend on polymer nature and doping conditions. Changes in parameters of the optical spectra were connected with conformation of polymer chain and modification of electron properties of conducting polymers under temperature action.
