摘要：

The relationship between spin dynamics and conductivity in polyaniline has been investigated as a function of temperature. The spin dynamics behavior has been studied from the frequency dependence of the ESR line width, which gives the electron spin-spin relaxation time (T2e). The data can be explained in terms of quasi 1-D spin diffusion with two parameters: the intrachain (D parallel-to), and the interchain (D perpendicular-to) spin diffusion rates. Our remarkable finding is that the dc conductivity agrees quite well with the interchain diffusion rate D perpendicular-to, both as a function of the protonation level y and as a function of temperature. Further, the charge carrier concentration is suggested to be temperature dependent.
