Electrical transport in doped and undoped polystyrene films in a cylindrical configuration

The steady state electrical conduction in films (about 30 μm thick) of polystyrene (PS) and of PS doped with acrylic acid (AA) was studied in the temperature range 35–115 °C. A mercury contact cylindrical electrode assembly was used in the conductivity measurements. Initially the conductivity decrea...

Summary:The steady state electrical conduction in films (about 30 μm thick) of polystyrene (PS) and of PS doped with acrylic acid (AA) was studied in the temperature range 35–115 °C. A mercury contact cylindrical electrode assembly was used in the conductivity measurements. Initially the conductivity decreases as a function of the dopant concentration but a higher concentrations it begins to increase with the dopant concentration. Different dopant concentrations were studied to attain an optimum doping concentration. The conduction behaviours for undoped and doped films were found to be different and a lowering of the activation energy due to doping with AA was also observed.
