COATED PARTICLES AND METHOD OF COATING PARTICLES

摘要

Coated particles include a core particle and a hybrid inorganic/organic layer coating the core particle. The hybrid inorganic/organic layer comprises a network of an inorganic component and at least one organofunctional silane component having organic functionalities which have not been polymerised. A method of coating particles comprising combining the particles with a surfactant and a hydrophilic liquid to form an emulsion with a hydrophobic phase containing the particles dispersed in a continuous hydrophilic phase, adding an organofunctional silane and an inorganic component precursor to the emulsion and heating the emulsion, adding a catalyst to the emulsion, and forming a hybrid organic/inorganic layer from the organofunctional silane and the inorganic component precursor on the particles to produce coated particles.
