STUDY OF PANI THIN FILM POLYMERIZATION IN DEPENDENCE ON ELECTRICAL FIELD

Popis výsledku v původním jazyce

Polyaniline (PANI) is one of the most studied and applied conducting polymers because of the unique conduction mechanism and high environmental stability. PANI could be synthetized by chemical or electrochemical methods. For this study PANI thin films deposited on glass substrate were prepared by chemical bath deposition from anilinium sulfate (precursor) using ammonium peroxodisulfate as strong oxidizing agent. Prepared samples were dried in high voltage static electric field (0.6 - 2.7 kV/cm). The most important effect was the increase of PANI thin film conductivity. Results showed changes in the microstructure, morphology, and conductivity of PANI thin films in dependence on high voltage electrical field. Optical transmittance was studied by UV-VISspectroscopy and Raman microspectroscopy was used to study structural changes in PANI chains. Variances in the range 1480-1650 cm-1 was revealed in Raman spectra. The dependence of conductivity on electric field intensity showed the maxim
