摘要：

The DC conductivity of several palladium polyacrylates with compositions in the range 5 to 40% w/w Pd has been measured over a wide range of temperatures (293 K to 363 K). Infra-red spectra and X-rays diffractograms have been obtained, making it possible to correlate the structural details with the nature of the conduction mechanism. The temperature and palladium concentration dependence of the DC conductivities are explained in terms of thermal hopping motion of localized charge carriers which are believed to be bipolarons.
