| Popis: | Electrically conducting polymer - polyparaphenylene, doped with iodine, bromine and also with alkali metals - have been characterized using the conductivity measurement technique in the temperature range from −150°C to 500°C. Doping of the polyparaphenylene was performed by exposing the polymer to halogen vapour pressure 1 atm at 500°C, by alkali metals (K, Na) by the reaction with an melted metallic sodium and potassium at 250°C. The conductivity was investigated as a function of the dopants content, the annealing temperature and the doping time. On the basis of the experimental results it is supposed therefore about the charge-transport mechanism in the doped polyparaphenylene. |
