Abstract
A silicone-grafted core-shell particle is described wherein the silicone-grafted core-shell particle comprises a core of an inorganic particle and a shell of a grafted poly(dimethylsiloxane) polymer formed from a bi-terminated poly(dimethylsiloxane) having reactive groups at each terminal end. The silicone-grafted core-shell particles may be dispersed in a polysiloxane polymer matrix and employed as an LED encapsulant.
