摘要
Polypyrrole is prepared electrochemically from a room temperature ternary eutectic melt consisting of acetamide, urea and ammonium nitrate. The temperature effects of conductivity of polypyrrole are analyzed by Arrhenius and Mott equations to understand its conduction mechanism. The thermal degradation of both doped and dedoped samples of the polypyrrole in air and N-2 atmosphere has been followed using thermogravimetric (TG) and differential thermal analysis (DTA). The kinetic analysis of the TG data has been carried out to obtain information on the energy of activation for the polymer decomposition. (c) 2005 Elsevier B.V. All rights reserved.
