Key Lab of Modern Metallurgy & Materials Processing, School of Materials Science and Engineering, Shanghai University, Shanghai, 200072, China *qdzhong@shu.edu.cn Keywords: polymer coatings, steel, alkaline, corrosion, semiconducting Abstract：The semiconducting behavior of No.20 carbon steel coated with different polymer coating in 5% sodium hydroxide solution was studied by utilizing potential-capacitance and Mott-Schottky analysis.
Introduction It was well known that organic polymer coatings were typical insulating materials, and electrochemical and corrosion behaviour beneath the coatings have also drawn many concernings [1-4], till now, it is also a hot topic for electrochemical and corrosion studies, especially in some specific area, such as in alkaline solution [5].
