Effect of Acidic Dopants properties on the Electrical Conductivity of Poly aniline

Abstract

Polyaniline was doped with different halogenic acids. The electrical conductivity of the doped polymers shows significant affects of the counter ions of the dopant on the conductivity. It was appeared that the electron affinity of the counter ion is the dominating factor. The results show that the electrical conductivity will increase with increasing the dopants concentration. The percolation point was also investigated; it was shown that the electron affinity of the counter ion of the dopant plays the major effect on this point.
