The polymerization monitoring by Voc showed a maximum associated with the intermediate pernigraniline oxidation state and a final formation of polyaniline (PANI) in the doped emeraldine salt (ES) form. Furthermore, high electrical conductivity values were obtained for the PANI-ES coating prepared under selected conditions. A globular formation was observed for the doped PANI-ES coating with globules of sizes of the same order and same shape of the PET, demonstrating the influence of the substrate on the coating morphology.1220-1229engAtomic force microscopyConductive filmsElectric conductivity of solidsElectric potentialInfrared spectroscopyMorphologyOxidationPlastic filmsPolyethylene terephthalatesPolymerizationScanning electron microscopyPolyanilineComposite materialsArtigo10.1002/1097-4628(20010214)79:7<1220::AID-APP90>3.0.CO;2-3Acesso restrito2-s2.0-0035252234
