Research conducted jointly between Optical Dynamics and the University of Kentucky has produced methods of synthesizing inorganic nanoparticles for inclusion in optically transparent nanocomposites. The nanocomposite consists of an inorganic nanoparticle embedded into a polymer and was commercialized as an eyeglass coating in 2006. This nanocomposite is significant since we can engineer the optical properties of a transparent material outside the typical range for polymers, while still maintaining large strain domains. Demonstration of refractive index control from 1.48 up to 1.885 is shown in figure 1 and the group has demonstrated the flexibility to strains in excess of 20 percent.
