Abstract

See full text

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.
