Aoki conduction model

Nucleation models have also been invoked for the oxidation of polyaniline films.209,213 In both cases, the nucleation of electronically conductive zones was assumed, following Aoki s well-documented model. The possibility that the nucleation of ionically conductive regions could be rate limiting does not appear to have been considered.

Trueblood et al., 1997) were introduced into the model and some trial calculations were conducted for the improvement (Doi, Nakata, Kubota, Aoki, 1999). The model with wider applicability was finally developed.
