Study of the Electrical Characteristics of Polyaniline Prepeared by Electrochemical Polymerization

Polyaniline (PAni) is one of imported polymer for synthesis solar cells .The quality of film depended on the method of polymerization. In this research PAni have been prepared by the electrochemical polymerization of aniline on stainless steel electrode. The electrical conductivity of these films was measured by two–probe method .The electrical conductivity is influenced by preparation conduction such as concentration of H2SO4 and current density .The conductivity between (0.1 -10-10) S/cm depends on PH and current density. The best electrical conductivity about (0.1) S/cm was found PH at (4.2) and current density 0.3 mA/cm2.
