Investigation on the anticorrosion, adhesion and mechanical performance of epoxy nanocomposite coatings containing epoxy-silane treated nano-MoO₃ on mild steel

Enhanced Corrosion Protection of Epoxy/ZnO-NiO Nanocomposite Coatings on Steel

“…The EP/1.8 ZnO-NiO nanocomposite coated mild steel had superior charge transfer resistance compared to pure epoxy and EP/1 ZnO-NiO coated samples. It can be observed that the EP/1.8 ZnO-NiO coating displayed an enlarged time constant in the series of the high frequencies that is accredited to its improved barrier properties [38][39][40]. As can be seen from Table 3, the EP/1.8 ZnO-NiO nanocomposite coatings exhibited superior anticorrosive performance when compared to other reported nanomaterials and thin film coating systems.…”

Chemical Functionalization of Graphene Nanoplatelets with Hydroxyl, Amino, and Carboxylic Terminal Groups

“…Metal corrosion problems have been associated with the history of human beings using metal, and countless attempts have been made to improve the corrosion resistance of metals. Due to higher corrosion resistance and outstanding adhesion, epoxy coating has drawn much attention among different methods [58,59]. Zhao's group has successfully used poly(2-butylaniline) functionalized graphene as an additive in epoxy coating [60].…”

Enhancement of Barrier and Mechanical Performance of Steel Coated with Epoxy Filled with Micron and Nano Alumina Fillers

“…However, other combinations reduce the corrosion performance, due to flaws introduced in the coating film. Similarly, epoxy/Molybdenum oxide nanocomposite coating enhanced the mechanical, adhesion, and anticorrosion properties as compared to epoxy coating 9 . Furthermore, Abd El-Lateef and Khalef 24 reported that the optimum percent of ZrO2-TiO 2 is 10wt % but the inclusion of a higher weight *e-mail: dselsayed@tu.edu.sa percent of ZrO2 resulted in the formation of a weak film with poor barrier properties.…”

“…Metal with polymeric composite barrier liners was used to reduce oxygen and moisture diffusion produced in food packaging 6,8 . Epoxy resin is one of the widely used polymers utilized to protect mild steel due to its strong adhesion, good chemical resistance, and low shrinkage 4,9,10 . To get benefit from its good properties, inorganic particles may improve the stiffness and other properties of the epoxy coatings 11 .…”

“…Moreover, the transparency of the polymeric coating will not be disturbed with the existence of nanoparticles with dimensions less than100 nm 18 . The anticorrosion performance and mechanical properties of metals are highly improved by the incorporation of metal oxide nanofillers to epoxy matrices 5,9,19,20 . In addition, alumina (Al 2 O 3 ) fillers characterized by their high mechanical properties have been widely used to enhance related properties of epoxy matrices 4 .…”
