Abstract
An experimental study of the temperature- (T) dependent dc conductivity, the electric field (E) dependence of, and the T-dependent thermopower S as a function of protonation level (0.0<x[H+][N]0.5) of emeraldine polymer is presented. The conductivity (300 K) varies from 10-10 to 10 -1 cm-1 with increasing protonation, while (T)exp[-(T0T)12], with T0 decreasing with increasing x. Above a threshold field Et, exp(-E0E), with E0 constant. The thermopower S changes sign with increasing x and is proportional to T for x0.5. The transport properties are the first systematic evidence for the formation of a granular polymeric metal.
