Abstract
Methods of encapsulating particles () in polymer () and compositions of matter using such encapsulated particles (). Methods include mixing particles () of one or more materials with one or more initial radical polymerizable monomers () and one or more initial charge-generating components () to form a first suspension of monomer-wetted particles (), mixing the first suspension with an aqueous dispersant medium () to form a second suspension, adding one or more initial reaction initiators to at least one of the first suspension and the second suspension, subjecting the second suspension to homogenization sufficient to form a stable submicron emulsion having an aqueous continuous phase (), and reacting available radical polymerizable monomers () of the emulsion to encapsulate the particles () in one or more layers of polymer () and to incorporate ionic species from available charge-generating components ().
