摘要：

The positron lifetime spectra in polyaniline have been measured as a function of protonation level (pH from 7 to -0.8) . We observed that (1) the short lifetime tau1 decreased with the protonation level; (2) the intermediate lifetime was constant (tau2 almost-equal-to 360 ps), whereas its intensity I2 increased with increasing protonation level which was related to the conductivity of material. These results are discussed in terms of conducting island model.
