“…In this regard, cis-polyacetylene has been stretch-oriented and subsequently doped into a highly conducting form [380, 489±491], and a stretching-induced crossover from a semiconducting to metallic state in iodine-doped polyacetylene ®lms was observed [381]. Highly aligned electrochemically synthesized polypyrrole ®lms with conductivities along the alignment direction up to 1005 S/cm have also been prepared by stretching them to more than twice their original length [492,493]. Elongations up to ®ve times the initial length were demonstrated to be possible for P3HT [494] and poly(3-octylthiophene) (P3OT) upon stretching [495].…”

“…A Ag/AgCI reference electrode and Pt counter electrode were also employed in the electrochemical cell. Details of the EQCM are documented in previous 5 literaturel 2 ,1 7 . The EQCM sensitivity is 18 ng Hz-1 cm-2 with a working electrode area of 0.71 cm 2 .…”

“…Li has shown that the Py polymerization rate is directly proportional to the anion concentration of the monomer solution (for [A -] < 1 M). 23 For electrochemical PPy synthesis, various parameters such as the applied potential or the anodic current, 24 the concentration of monomer, 25 the nature of the supporting electrolyte, 26 and the nature of the working electrode 27 have an influence on the growth kinetics and the final structure of the polymer. 28,29 Polypyrrole nanostructures have been obtained using pyrrole solution containing either monohydrogenophosphate 28 or mixing of monohydrogenophosphate and dihydrogenophosphate (phosphate buffer solution (PBS)) [30][31][32][33][34][35] or carbonate.…”
