Journal ArticleDOI
Electrical conductivity and thermoelectric power of polypyrrole with different doping levels
TL;DR: In this paper, the electrical conductivity and absolute thermoelectric power of polypyrrole have been measured between approximately 4 K and 350 K. The Mott variable-range hopping model for electrical conductivities is obeyed at higher temperatures for both types.
Journal ArticleDOI
Optimization of synthesis conditions of polypyrrole from aqueous solutions
D.S. Maddison,J. Unsworth +1 more
TL;DR: In this paper, the synthesis conditions for polypyrrole produced from aqueous solutions and doped with p -toluenesulphonate have been optimized with respect to current density, temperature and anion molarity.
Journal ArticleDOI
Thermoelectric power of polypyrrole
TL;DR: In this article, an experimental study has been performed on the temperature dependence of thermopower and electrical conductivity in polypyrrole which has been doped to different levels.
Journal ArticleDOI
Pressure dependence of electrical conductivity in polypyrrole
TL;DR: In this article, the electrical conductivity as a function of pressure to about 1.1 GPa is determined for p -toluenesulphonate-doped polypyrrole at two different doping levels.
Journal ArticleDOI
Pressure dependence of electrical conductivity in polypyrrole — II
TL;DR: In this paper, pressure dependence of the electrical conductivity of polypyrrole p -toluene sulfonate has been measured at a variety of different temperatures between 295 K and 413 K.
