Polyfuran films doped with perchlorate anions (PFu/ClO 4 ) were studied by scanning and transmission electron microscopies under different synthesis conditions. However, an electropolymerization overpotential equal to at least 2.1 V was needed to obtain stable PFu/ClO 4 films. In the synthesis conditions analysed, the film growth face presented an ordered nodular structure oriented 45 ° with respect to the lengthwise axis of the electrode. The nodule size and film rugosity were affected by the ratios between furan and NaClO 4 concentrations. When the furan concentration was double that of perchlorate, the films were less rough and more homogeneous. © 2000 Society of Chemical Industry
