where W0and W1are the weight of coated steel panel before andafter immersion, respectively. As it can be seen in Fig. 8, the neatepoxy coating experienced the highest amount of weight loss dueto corrosion in comparison with the modified coatings. Further-more, the steel substrate coated with epoxy/PANI/OMMT presentedthe best anticorrosion behavior (the least weight loss) among the coated samples which is in accordance with the results obtainedfrom electrochemical tests (Tafel and EIS) and visual observations
