摘要：

Montmorillonite organoclay (OMMT) and nanoglass flake (GF) were incorporated into epoxy resin by mechanical agitation and sonication process. Optical microscopy was used to analyse the optical homogeneity of dispersions. To investigate anticorrosive properties of nanocomposite organic coatings, salt fog test, electrochemical impedance spectroscopy (EIS), polarization measurement, pull-off adhesion and water absorption tests have been employed. The time course of impedance parameters and polarization studies show that coating corrosion resistance is improved as the amounts of OMMT and GF are increased to 3 wt%. The results indicated that nano-GF filled specimens display better corrosion performance than the OMMT filled ones. (C) 2010 Elsevier Ltd. All rights reserved.
