“…composites which contain them belong to the materials most often used to produce self-repair coatings [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The ease of modification stems from the various properties of macromolecular compounds, such as oxidizing properties, swelling and cross-linking ability, and from the fact that no high temperatures are required to form them.…”

“…Molybdate anions perform a similar function as in the case of PPy coatings enriched with PMo 12 O 40 3-and HPO 4 2-ions. The self-healing mechanism of epoxy esters resin with n-PANI(DBSA) consists of releasing DBSA -anions which by reacting with iron cations cause the formation of an additional layer at the end of the coating pores [3]. The PANI/sol-gel coating provides corrosion protection for aluminium alloy through a selfrepair mechanism thanks to the ability of polyaniline to undergo a redox reaction.…”

Nonmetallic (based on polymers or oxides) and metallic protective coatings are used to protect metal products against the harmful action of the corrosion environment. In recent years, self-healing coatings have been the subject of increasing interest. The ability of such coatings to self-repair local damage caused by external factors is a major factor contributing to their attractiveness. Polymer layers, silica-organic layers, conversion layers, metallic layers and ceramic layers, to mention but a few, are used as self-healing coatings. This paper presents the main kinds of self-healing coatings and explains their selfhealing mechanisms.

SYNTHESIS, CHARACTERIZATION OF PANI/EPOXY AND PANI/ZnO/EPOXY POLYMERIC COMPOSITES AND INVESTIGATION OF THEIR CORROSION BEHAVIOR ON STEEL L304ABSTRACT In this study, we have prepared polyaniline (PANI) and PANI/ZnO composites containing different ratios (0.1g, 0.25g, 0.5g, 1.0g) nano ZnO by chemically. The structure of polymeric nanocomposites which prepared in the form of granules was characterized by TGA, FTIR, and SEM. In order to protect steel L304from corrosion, metal surfaces were covered with PANI, PANI/nano metal oxide polymeric composites that dissolved in the polyvinyl butyral (PVB), anti-corrosion properties of PANI/Epoxy films and PANI/ZnO/Epoksi polymeric composite films consisting on metal surfaces was determined by potentiodynamic polarization measurements in 3.5% NaCl solution. From the obtained results, by the addition of epoxy resin containing nano ZnO the polymeric composite that coated to surface has been determined to be more effective at protecting steel from corrosion than PANI/Epoxy coating.

Conducing polymers (CPs) have been significantly contributing to the development of high performance new-generation anti-corrosive coatings. CPs nanofiller dispersed insulating polymer coating effectively prevents the transport of corrosive ions (H + , O 2-, Cl -, OHetc) at coating-metal interface, via barrier or redox mechanism. In view of this, for the first time, we report the synthesis of poly (o-anisidine-co-o-phenyldiammine) P(oA-co-oPDA) copolymer conducting nanorods. Poly (o-anisidine) (PoA) conducting nanoparticles were also synthesized laterally. The formulation of these nanofillers dispersed epoxy-polyamide (PA) nanocomposite coating systems have also been reported. The structural elucidation was performed by FT-IR, UV-Vis, 1 H NMR spectroscopy. The crystallnity, surface area and morphology of fillers were analysed by XRD, BET, SEM and TEM techniques. The thermal stability and hydrophobic behaviour were investigated using TGA, DSC and contact angle measurements. The physicomechanical properties and corrosion protective performance of these coatings were evaluated using standard methods. The salt spray test, potentiodynamic polarization (PDP) and electron impedance spectroscopy studies (EIS) were conducted in 5 wt % NaCl and 5 wt % HCl media.3 revealed that the P(oA-co-oPDA)-epoxy-PA nanocomposite coating have exhibited superior performance than those of PoA-epoxy-PA, epoxy-PA and other such nanocomposite coatings.
