Electric relaxation in chemically synthesized polyaniline: study using electric modulus formalism

Electrically conducting polymer nanostructures confined in anodized aluminum oxide templates (AAO)

“…This procedure of temperature increase was applied for all the following measurements, therefore, it can assured that the conduction values are not influenced by the amount of absorbed water. To support this analysis, similar results were found in the literature in the study of the influence of water molecules over EB [37]. In that work, a positive temperature coefficient, '#/'T > 0, also for high doping levels, was evidenced.…”

Influence of silver ion reduction on electrical modulus parameters of solid polymer electrolyte based on chitosan-silver triflate electrolyte membrane

“…Our Argand plots appeared as deformed arcs at low temperatures with their centers positioned below the horizontal axis. This position, in principle, corresponds to the electric relaxation in materials with both the relaxation time and activation energy distributed and intercorrelated [28]. It can be seen ( Figure 6) that with increasing temperature the Argand curves shifts towards the origin.…”

Molecular relaxations in ester-terminated, amide-based dendrimers

“…Values for ⌬ for ␤ relaxations were comparable to those obtained for amorphous linear polymers studied in our laboratory. 42 The electric modulus approach was also extended to the Cole-Cole method for ␣ 34,43,44 and ␤ 44 relaxations to give ⌬MЈ. Representative ColeCole plots of MЉ vs. MЈ are depicted in Figure 13 in which complex behavior was observed for the ␣ process.…”
