โฆ Synopsis
ES
investigations carried out on either redox or conducting polymer layers are reviewed. The models proposed for redox polymers in contact with solutions with or without a redox couple and their experimental verifications are discussed. The literature relative to conducting polymers such as polyacetylene, polypyrrole and polyaniline is analysed and some relevant questions concerning data interpretation are pointed out.

Chromate conversion layers of a thickness ranging from 20 to 250 nm on Al-alloys are characterized by EIS in 0.1 M Na,SO, and optical measurements. A model is derived from these data which describes the corrosion mechanism of these samples. The main components of the equivalent circuit can be attrib
The performance of a polymer redox supercapacitor based on poly(dithieno[3,4-b : 3',4'-d] thiophene) in liquid and in polymer gel electrolyte was tested for capacity, energy density, power density and self-discharge. The results are very promising and demonstrate the viability of a symmetric superca
