摘要：

Polyaniline (PANI) was covered on the surface of ultra-short glass fibers uniformly by in situ polymerization of aniline. Epoxy coatings with different contents of PANI ultra-short glass fibers and ultra-short glass fibers were formulated and their protection abilities were evaluated by means of open-circuit potential, electrochemical impedance spectroscopy and salt spray test. The results showed that the PANI ultra-short glass fibers had a significant inhibitive effect and its best volume fraction was 10% in epoxy coating. XPS results indicated that a dense, stable passive oxide film of Fe2O3/Fe3O4 was formed on the steel surface beneath the coating. (c) 2012 Elsevier B.V. All rights reserved.
