STUDY OF PROPERTIES OF CO-POLYMER COATING BY ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY
Abstract
In this work, the protective property of the electrochemically synthesized poly (anilineo- anisindin) copolymer (PAOA) in a 3.5% NaCl solution at various exposure times was studied by impedance spectroscopy. Based on the Nyquist diagrams, the degree of protection, the degree of water absorption, and the thickness of the copolymer coating were calculated. It was found that the values of the protective properties do not obey a certain regularity due to poor adhesion of the coating synthesized from an oxalic acid solution. According to the calculation result after 120 minutes of immersion of the coating in an aggressive environment, the following values were obtained: Z = 78.95%, % = 33.80 and d = 11.00 nm
