Su. Rehman et al., CONCENTRATION AND TEMPERATURE-DEPENDENCE OF ELECTRICAL-CONDUCTIVITY IN THERMALLY STABLE CHROMIUM POLYACRYLATE, Pure and applied chemistry, A32, 1995, pp. 579-591
Electrical conductivity of chromium polyacrylate with dopant concentra
tion 30% (w/w), 40% (w/w) and 50% (w/w) of chromium has been measured
over a broad range of temperatures (303K to 383K). The electrical cond
uctivity shows dependence on temperature, as well as, level of doping.
The conductivity is considered to be due to thermal hopping motion of
localized charge carriers, which are believed to be polarons, in the
temperature range 303K to 323K and for T>343K, whereas, it is metal-li
ke in the temperature range 323K to 343K.
