Thin films of soluble conducting polymer polyHexylthiophene (PHT) doped with ClO4 anion have been prepared by anodic polymerization of Hexylthiophene monomer on stainless steel electrode. Those films characterized by FTIR . The quality of the films were influenced by many parameters such as current density, concentration of supporting electrolyte (TBAClO4) tetrabutylammonum tetraperchlorate. The electrical conductivity of the films measured by two probe method. The electrical conductivity of the films studied as a function of current density and concentration of TBAClO4. The optimum electrical conductivity found at current density about 9.3 mA/cm2 and TBAClO4 concentration 0.1M. The conductivity of PHT films decreased when immersed in ammonia solution. The effect of temperature on electrical conductivity was also investigated.
