A polymer nanocomposite coating can effectively combine the benefits of organic polymers, such as elasticity and water resistance, to that of advanced inorganic materials, such as hardness and permeability. Environmental impact can also be improved by utilizing nanostructure particulates in coatings and eliminating the requirement of toxic solvents. Nanocomposites have also proven to be an effective alternative to phosphate-chromate pretreatment of metallic substrate, which is hazardous due to the presence of toxic hexavalent chromium. This article reports some of the preliminary investigations on the corrosion-resistance performance of soya oil alkyd, containing polyaniline/ferrite nanocomposite. The corrosion-protective performance was evaluated in terms of physico-mechanical properties, corrosion rate, and SEM studies. The polyaniline/ferrite nanocomposite coatings were found to show a far superior corrosion-resistance performance compared to that of a pure PANI/alkyd system.

Titre : Studies on corrosion protective epoxidised oil modified DGEBA epoxy paint Type de document : texte imprimé Auteurs : Sharif Ahmad, Auteur ; S. M. Ashraf, Auteur ; Abul Hasnat, Auteur Année de publication : 2002 Article en page(s) : p. 47-52 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Epoxy resins are the class of polymers which find application in composites, primers, coatings and paints. However, epoxy-polyamide paints show low impact resistance, high degree of brittleness, low fracture toughness and fail to give a satisfactory performance under severe chemical/corrosive environment. With a view to improve these properties of epoxy paints, the DGEBA epoxy resin was modified with epoxidised oil. The different blend ratios of DGEBA-LOE-PA were evaluated for flexibility, scratch hardness, drying time and resistance to humid environment by standard methods. The optimized resin system was used to formulate a paint, and its performance was compared with the conventional epoxy polyamide paints. Epoxidised oil modified DGEBA paints system as developed was found to show far improved physico-mechanical and anticorrosive properties than the conventional DGEBA-PA paints. Its resistance to chemical was also found to be better than its conventional counterpart. This paint system replaces part of DGEBA, a petroleum based product, by a vegetable oil based epoxy, which not only makes it cost effective, but enhances the utility of this system, as a product from a renewable resource is being used in it.
