Abstract
Disclosed are modified inorganic particles and methods of preparing the same. The modified inorganic particle comprises an inorganic particle with hydroxyl groups, and a surface modifier coupled to the inorganic particle via a urethane linkage, wherein the surface modifier has an ethylenically unsaturated end group. The method comprises providing an inorganic particle with hydroxyl groups; providing a surface modifier with an isocyanate group at one end and an ethylenically unsaturated group at the other end; and mixing the inorganic particle with the surface modifier for reaction such that the surface modifier is coupled to the inorganic particle.
