Also disclosed are methods for surface coating a substrate with a multifunctional barrier coating forming solution and detecting the same post application to determine a need for barrier coating reapplication.

A coating composition, a method for manufacturing a substrate using the same, and an optical device are provided. The method for manufacturing the substrate provides the substrate having excellent performance, as the substrate has fixed spacers on its surface by using a single layer in which nanoparticles and spacers are dispersed in an alignment film to reduce processes and cost. The optical device may be manufactured by such method.

Methods of forming oxidation barriers are provided. An illustrative method comprises applying a clay mineral coating composition comprising a solvent and exfoliated clay mineral sheets, e.g., exfoliated vermiculite sheets, to a surface of a substrate; and removing solvent from the clay mineral coating composition as-applied to the surface, thereby forming a coating comprising the exfoliated clay mineral sheets on the surface. The oxidation barriers are also provided.

A relatively low cost, water-based coating, intended to protect metal from corrosion, exhibiting excellent corrosion resistance, is formed by emulsification of oxidized soap wax containing a small amount of petroleum distillate, and other liquid additives. The resulting emulsion is modified to produce firm dry films, by addition of pigment followed by addition of highly polar acrylic resins. The pigmented composition is further modified with gelled metal sulphonates, to attain significant anti-corrosion properties.
