POLYFURAN - ELECTROSYNTHESIS AND ELECTROCHEMICAL-BEHAVIOR

The influence of the deposition potential on both electrogeneration an d electrochemical behaviour of polyfuran-perchlorate-doped films in ac etonitrile has been analysed. Yellow insulating deposits were obtained at 1.7 and 1.9 V, while adherent black films were formed at 2.1 and 2 .3 V. From the cyclic voltammetry of black polyfuran films, both the m echanism of the redox process and the increase of the films' electroac tivity with cycling have been established, these characteristics being very useful for technological applications. Scanning electron microgr aphs reveal an ordered structure in black polyfuran films.
