  • Soluble functionalized nanoparticles for use in optical materials
    Patent number: 9513406
    Abstract: Disclosed embodiments concern a soluble functionalized nanoparticle suitable for use with polymerizable components, such as monomers (or polymers thereof), used to make gradient optical polymer nanocomposites. In particular disclosed embodiments, the nanoparticle is functionalized with one or more surface ligands that promote the solubility and dispersion of the nanoparticle in the disclosed monomer. Also disclosed herein are embodiments of a method for making the functionalized nanoparticle as well as embodiments of a composition comprising the functionalized nanoparticles.
    Type: Grant
    Filed: July 17, 2013
    Date of Patent: December 6, 2016
    Assignee: University of Oregon

  • GRADIENT OPTICAL POLYMER NANOCOMPOSITES
    Publication number: 20150023643
    Abstract: Gradient index optical materials are formed by drop by drop dispensing of nanoparticle/monomer suspensions. Refractive index variations are defined by nanoparticle concentrations that can vary in three dimensions. Droplets of differing compositions can be mixed, and droplets or layers or droplets are partially cross-linked by exposure to ultraviolet radiation prior to dispensing additional droplets. Gradient index optical elements such as lenses, prisms, and waveguides can be formed in flexible polymer layers.
