摘要：

The electrical properties of iodine-doped poly(phenylacetylene) [PPA] solutions have been studied by means of low-frequency electrical conductivity and dielectric measurements in the frequency range 1 MHz-1 GHz. These data show that, in these systems, the conducting mechanism is different and more complicated than the typical additive behaviour of diluted ionic solutions. The high-frequency dielectric measurements display a pronounced dielectric dispersion characterized by a single Debye-type relaxation process. This dielectric behaviour can be attributed to the dipolar character of PPA, enhanced when the polymer interacts with the iodine doping species.
