SURFACE TREATMENTS FOR INCREASING TRANSMISSION AND DURABILITY OF A TRANSPARENT ARTICLES

摘要

The reflectivity of a hardcoated optical element is reduced via modification Of the surface topography. Selective etching of the hardcoat surface in a alcoholic solution containing dissolved alkali or basic reagent results in increased transmission; yet without significantly affecting the haze or light scattering, or other desirable optical property. The durability and abrasion resistance of nano-structured optical surfaces, particularly those formed of or on polymeric substrate, are enhanced by at least one of adhering to it a fluorinated carbon molecule or other reactive lube composition as a monolayer or a thin multi-layer coating, and treatment with a surface active cross linking agent.
