Abstract: The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modifation of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.
