Resin of Conducting Composite Coating

Common matrix resins for blending with conducting polymers are widely used in traditional anticorrosion coatings, such as epoxy resin [25, 27, 32, 34, 68, 70, 71, 76], polyacrylic-based resin [24, 39, 48, 77, 78], and poly(methyl methacrylate) [30, 60, 62, 64]. The feature of matrix resin as well as the amount of ICPs is important to the anticorrosion performance of conductive composite coating. Samui and Phad-nis [67] blended various amounts of dioctyl phosphate (DOPH)-doped PANI with different polymeric matrices (epoxy resin, polyurethane resin, styrene-butyl acrylate 

The results were positive and promising. Bagherzadeh et al. [81] found that the anticorrosion performance of a two-component water-based epoxy resin coating system was improved by adding only 0.02 wt% nano-PANI. Ahmad et al. [82] investigated the corrosion protection behavior of waterborne resorcinol formaldehyde (RF)-cured composite coatings of poly(l-naphthylamine) (PNA)/poly(vinyl alcohol) (PVA) on mild steel, and even superior corrosion protective performance was observed in different corrosive media when compared with the reported solvent-based conductive polymer coatings.
