Abstract

In this study, stainless steel electrode alternate current (ac) impedance associated with direct current (dc) polarization measurements were proposed to successfully evaluate the contribution of ionic conductance (t^ion) to the bulk conductance of polypyrrole (PPy) in various relative humidities (RH). The fraction of t^ion, defined as the ratio of (1/R_i) to ((1/R_i)+(1/R_e)), was used as a quantitative index for the contribution of ionic conductance. The results showed that the t^ion are 0.15, 0.29, and 0.46 for PPy in 5, 25, and 50% RH, respectively. Also, the t^ion can increase from 0.12 to 0.22 in dry nitrogen after PPy was modified with polyethylene oxide (PEO).
