“Effect of nano-ZnO particles on the corrosion behavior of alkyd-based waterborne coatings”

Development and Characterization of Anticorrosion and Antifriction Properties for High Performance Polyurethane/Graphene Composite Coatings

“…The presence of water molecules at the coating-substrate interface may trigger electrochemical corrosion of a metal under the coating, leading to a decrease in adhesion strength and coating delamination. The barrier performance and permeability of organic coatings can be improved by the incorporation of inorganic fillers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. For instance, Dhoke and co-workers [1] found that the addition of nano-ZnO on the alkyd-based waterborne coating can enhance the density of the coatings thereby reducing the transport paths for the corrosive electrolyte to pass through the coating system and hence reducing the corrosion process.…”

Nanostructured ZnO Materials: Synthesis, Properties and Applications

“…More specific studies were devoted in evaluating the enhancement in surface properties obtained by the addition of ZnO nanoparticles, e.g., scratch resistance (Chakraborty et al in PMMA [172] and Bermúdez et al in polycarbonate [173]), corrosion (Olad et al in PVC [174] and Dhoke [175] et al in waterborne resins [175]), and gas barrier [176]. Other applications were found in nanocomposites for wood protection [177][178][179] and phase-changing materials (PCM) [180].…”

Effects of Environmental Conditions on Degradation of Automotive Coatings

“…The conventional UVAs are benzotriazoles, triazines and bezophenones. Nowadays, by advances obtained in nanotechnology, new generation of materials have been achieved that not only are capable to absorb UV rays, but also can improve the mechanical, thermal and electrochemical performance of the coating (Peng et al, 2008;Dhoke et al, 2009;Xu & Xie, 2003) . The best choices for this purpose are titanium dioxide, zinc oxide, cerium oxide, iron oxide or even silica nanoparticles.…”
