The possibility of the modification of polyethylene terephthalate film substrate by polypyrrole films during in situ chemical oxidation of pyrrole by ammonium peroxodisulfate in 0.5 M aqueous solution of citric acid with concentrations of pyrrole in of equals 0.025 and 0.05 M has been studied. UV-vis and IR spectra of doped during synthesis by citric acid dedoped by sodium hydroxide and re-doped by citric acid polypyrrole films on polyethylene terephthalate film substrate were analyzed. The results of the morphology studies of the deposited coatings show that there are delocalized globular microformations of the macromolecules of mostly spherical shape on the background of the continuous layer of polypyrrole.
