摘要：

Polyaniline has been synthesized chemically and cast from 1-methyl-2-pyrrolidone (NMP) solution over iron samples. A series of electrochemical measurements, including corrosion potential and corrosion current has been made on polyaniline-coated iron samples in various environments. Results showed that polyaniline can offer some degrees of protection in the corrosive environments. Protective properties of the conducting polymer were compared with a conventional polymer such as polyvinyl chloride (PVC). Comparative experiments revealed that emeraldine base form of polyaniline has better protective properties. (C) 2000 Elsevier Science S.A. All rights reserved.
