Influence of the electropolymerization parameters on the generation of polyfurane perchlorate doped films

Influence of synthesis conditions on the morphology of perchlorate doped polyfuran films

“…The undefined morphological nodules found in these films, as noted aboved, were consistent with the insulating characteristics mentioned in preliminary chronoamperometric studies 18. The morphological study was therefore centred on PFu/ClO 4 films generated at η p = 2.1 and 2.3 V.…”

“…PFu/ClO 4 films synthesized at 1.7 and 1.9 V and [Fu] = [NaClO 4 ] = 0.1 or 0.2 M (A 1.7 , A 1.9 , B 1.7 and B 1.9 , respectively) could not be removed from the electrode. Thin yellow deposits were formed on the electrode surface 18…”

“…This roughness was caused by a mixture of mechanisms occurring during electrogeneration of the film: a nucleation process not occurring simultaneously all over the electrode surface. It began at edges and rapidly spread inwards to completely cover the platinum surface;18 the film grew more easily over the previously formed nuclei (see Fig 3) because nucleation is more favoured over the polymeric layers than on the electrode surface 18 …”

Palladium nanoclusters-coated polyfuran as a novel sensor for catecholamine neurotransmitters and paracetamol

“…Carrillo et al [11,34,[57][58][59]. The film showed ordered nodular structure that was always oriented at 45 • with respect to the longitudinal axis of the Pt electrode.…”
