Abstract
A method includes steps of forming an inner coating on an object and forming an outer coating in contact with the inner coating. A first solution including metal oxide nanoparticles and a first solvent is applied onto the object. The first solvent is removed to form the inner coating with the metal oxide nanoparticles. A second solution having silicon dioxide nanoparticles and a second solvent is applied onto the object. The second solvent is removed to form the outer coating with the silicon dioxide nanoparticles. The interfacial binding force between the metal oxide nanoparticles and the silicon dioxide nanoparticles is then strengthened, for example, by applying a third solution such as water, ethanol or a mixture thereof to the inner coating and the outer coating.
