The chemical composition and structure of polyphenol films formed electrochemically on Pt from bulk phenol in the absence and in the presence of solution sulphide were studied by XPS. The C1s (284.2–284.6 and 285.6–286 eV) and the O1s (533eV) signals are consistent with a polymeric structure consisting of an aromatic carbon ring backbone linked by ether-like bonds and with hydroxyl groups. This structure is common to all the examined films formed under either potentiodynamic or potentiostatic conditions, even though the coatings formed in the presence of sulphide seemed to possess a higher ether-like oxygen content. Polyphenol films generated by cyclic voltammetry in the presence of sulphide contained a small amount of incorporated sulphur, with a characteristic binding energy of 162.3eV which is essentially identical to that found for a sulphur layer deposited on Pt from sulphide in phenol-free solutions. The film is described as a S-polyphenol composite material, in which the S fraction is mainly incorporated at the early stages of filming. Sulphur-polyphenol composite coatings proved to possess more effective barrier properties than S-free polyphenol films.
