摘要：
The aim of this work is to present an electrical study of the aging of conducting polyaniline-polystyrene (PANl-PSt) blends. Results concerning time dependence of the electrical conductivity of some samples artificially aged at different temperatures are presented. It is shown that the electrical conductivity decreases with time with a rate depending principally on the nature of the dopant. When aged at the same temperature, similar degradation kinetics are observed as well for doped polyaniline as for PANl-PSt blend. A study of the electrical conductivity variations versus temperature is presented for samples which have been aged at the same temperature but for different durations. Experimental results are discussed in the frame of the heterogeneous picture already proposed for nonaged samples. (C) 2000 American Institute of Physics. [S0021-8979(00)04214-6].
