Abstract
A surface coating, colorant, pigment or polymer composite preparation that provides resistance to degradation when exposed to at least some portion of ultraviolet radiation having wavelengths between approximately 190 and 400 nm is made up of a dispersion of an effective amount of diamond nanoparticles in a binding matrix, wherein at least a portion of the diamond nanoparticles have a size greater than about 60 nm so that the diamond particles provide ultraviolet radiation degradation resistance properties in the dispersion. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
