Title
(EN) MICROSPHERES COMPRISING POLYDISPERSE POLYMER NANOSPHERES AND POROUS METAL OXIDE MICROSPHERES
(FR) MICROSPHÈRES COMPRENANT DES NANOSPHÈRES POLYMÈRES POLYDISPERSÉES ET MICROSPHÈRES D'OXYDE MÉTALLIQUE POREUSES
Abstract
(EN)
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.
(FR)
Des microsphères d'oxyde métallique poreuses sont préparées par l'intermédiaire d'un procédé comprenant la formation d'une solution ou dispersion liquide de nanoparticules polymères polydispersées et d'un oxyde métallique ; la formation de gouttelettes liquides à partir de la solution ou de la dispersion ; le séchage des gouttelettes liquides pour fournir des microsphères de matrice polymères comprenant des nanosphères polymères et de l'oxyde métallique ; et le retrait des nanosphères polymères des microsphères de matrice pour fournir les microsphères d'oxyde métallique poreuses. Les microsphères poreuses présentent des couleurs saturées et sont appropriées en tant que colorants pour une variété d'utilisations finales.
