Influence of the electropolymerisation time on the nucleation mechanism, structure and morphology of polyfurane/perchlorate doped films

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. rphological study revealed an ordered nodular structure and different levels of growth from the first seconds of synthesis untill higher tp values. Dendritic formations on the growth face and the cross-section pores implied alternating planar and normal growth of the films. pectra study verified that the structure of these polymers was influenced by tp, so that the film aromaticity differed according to this parameter.
