  • Treatment of deagglomerated particles with plasma-activated species
    Patent number: 6156114
    Abstract: A method for treating the surface of substantially each deagglomerated particle of an array of easily agglomerated particles by contacting deagglomerated particles with a plasma-activated gas species and modifying the surfaces of the deagglomerated particles to aid subsequent incorporation of the particles into a matrix composition; the module for deagglomerating and dispersing the particles into the plasma-activated gas; the apparatus that comprises the deagglomeration module (322) and a reaction chamber (20) in which the particles are treated with the plasma-activated gas; the method for deagglomerating particles that may reagglomerate after plasma treatment; and a color composition containing plasma-treated pigment particles.
