摘要：
The influence of electropolymerisation time, tp, on the synthesis, structure and morphology of polyfurane films doped with perchlorate anions, PFu/ClO4, was analysed. The analysis of the nucleation mechanism revealed a mixture of progressive and instantaneous nucleation of small hemispherical nodules controlled by spherical diffusion. The morphological study revealed an ordered nodular structure and different levels of growth from the first seconds of synthesis until higher tp values. Dendritic formations on the growth face and the cross-section pores implied alternating planar and normal growth of the films. FTIR spectra study verified that the structure of these polymers was influenced by t(p), so that the film aromaticity differed according to this parameter. (C) 2001 Elsevier Science Ltd.
