...f polyaniline, even with the use of disaggregating salts, overestimated Mn values by almost 30% from GPC measurements can be obtained when compared with the calculated Mn observed by light scattering =-=[37]-=-. The structural similarity between polyanilines and polyaminopyridines did not allow the possibility to discard other molecular weight values also overestimated for PAPy by GPC analysis. It is diffic...

...pulsion of anions during the BP→P transition increasesthe hydration degree of POT film. Moreover, deprotonated PN sites can be chemicallysprotonated by means of acid/base equilibrium to form BP sites =-=[83,84]-=-. These factsscould be the cause of the expulsion of these anions at more anodic potentials.sOn the other hand, the H3O+ transfer around 0.1 V could be due to the packingsof films.
