Polymer conformation factors affecting

AFS has been used in the investigation of conductivity in polymers, namely PANI and its derivatives (POEA and POMA). The degree of protonation and the conductivity vary within the PANI class, which is attributed to differences in conformation of the polymer chains and packing in a film. The mechanisms of charge conduction are still not completely understood, precisely because of the diversity of factors affecting conductivity. It is, nevertheless, widely accepted that in the PANI structure the doped molecules are not uniformly distributed, but rather agglomerated into conducting islands. In a systematic... 

In the case of soluble PPy, it has been reported that the solvent is a very important factor affecting the electronic structure of the polymer because the chemical or conformational structure of the PPy chain is... 

A review of literature on factors affecting physical properties of solution-cast polymeric films points to the solvent in casting solution as the most important factor [47]. This is because the nature of solvent affects chain conformation, size and asymmetry of the polymer coil in dense films [16]. In many cases, however, the effect of solvent might simply be related to the effect of residual solvent in polymeric films, because the removal of residual solvent from glassy polymers is very difficult.
