Abstract

POLYANILINE IS ONE OF THE MOST IMPORTANT CONDUCTIVE POLYMERS THAT ITS STRUCTURAL STUDIES STARTED AT 1980 JUST BECAUSE OF ITS GREAT ELECTRICAL CONDUCTIVITY AND STABILITIES IN OPEN AIR [1, 2 .[IN THIS PROJECT WE USED IMPEDANCE SPECTROSCOPY TECHNIQUES TO DETERMINE THE CONDUCTIVITY AND CHARGE TRANSFER RESISTANCE PROPERTIES OF POLYANILINE FILM IN AQUEOUS SOLUTION THAT CONTAINS CR AND CU. WE ALSO DISCUSSED ITS NYQUIST CURVES AT 0.8 VOLTAGE. FROM THE ACHIEVED RESULTS IT HAS BEEN EXPECTED THAT THE CHARGE TRANSFER RESISTANCE OF CU SHALL BE REDUCED BECAUSE OF FULL FILLED 3D LAYER AND INCREASING OF SHIELDING EFFECTS [3]. SO THE CHARGE TRANSFER RESISTANCE OF CU IS LESS THAN CR AND ITS CHARGE TRANSFERRING IS MUCH HIGHER THAN CR. THESE PROPERTIES LEADS TO THE EASIER REDOX TRANSFERS OF AN CONDUCTIVE POLYMER.
