  • Porous Metal Oxide Microspheres
    Publication number: 20190076809
    Abstract: Porous metal oxide microspheres are prepared via a process comprising forming a liquid dispersion of polymer nanoparticles and a metal oxide; forming liquid droplets of the dispersion; drying the droplets to provide polymer template microspheres comprising polymer nanospheres; and removing the polymer nanospheres from the template microspheres to provide the porous metal oxide microspheres. The porous microspheres exhibit saturated colors and are suitable as colorants for a variety of end-uses.
    Type: Application
    Filed: September 10, 2018
    Publication date: March 14, 2019
    Inventors: Rupa Hiremath Darji, James Newhouse, Vinothan N. Manoharan, Victoria Hwang, Anna B. Stephenson
  • Microspheres Comprising Polydisperse Polymer Nanospheres and Porous Metal Oxide Microspheres
    Publication number: 20190076810
    Abstract: Porous metal oxide microspheres are prepared via a process comprising forming a liquid solution or dispersion of polydisperse polymer nanoparticles and a metal oxide; forming liquid droplets from the solution or dispersion; drying the liquid droplets to provide polymer template microspheres comprising polymer nanospheres and metal oxide; and removing the polymer nanospheres from the template microspheres to provide the porous metal oxide microspheres. The porous microspheres exhibit saturated colors and are suitable as colorants for a variety of end-uses.
