Polyaniline (PANI) is one of the most promising conducting polymers because of its ease of synthesis, tunable properties and low cost monomer. It has been proved that introduction ofsilicate layers into PANI matrix results in an improvement in anticorrosion properties compared to the neat polymer [1]. Inthis paper, anticorrosion performance of epoxy paints modified by PANI and PANI/clay nanocomposites is investigated.
