Preparation, characterization and electrochemical corrosion studies on environmentally friendly waterborne polyurethane/Na+-MMT clay nanocomposite coatings

In-situ AFM and EIS study of a solventborne alkyd coating with nanoclay for corrosion protection of carbon steel

“…It has been reported that the incorporation of lamellar pigments into polymer coatings such as polyaniline, epoxy or silane significantly improves the mechanical and barrier properties, thermal stability, wear resistance of the coating at a relative low loading of nanoclay [7,[11][12][13][14][15][16][17][18][19][20]. The improvement is essentially related to the morphology of the clay layers and the integration of the nanoparticles in the polymeric matrix [21].…”

Effect of antimony doped tin oxide on behaviors of waterborne polyurethane acrylate nanocomposite coatings

“…UV curable waterborne polyurethanes represent a major trend of PU development because of increasing concern about environmental pollution, health and safety risks [9][10][11]. Over the past few years much attention has been given to improving the thermal and mechanical properties of organic polymers by the incorporation of nanosized inorganic particles.…”

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.…”
