NANOMETER PIGMENT COMPOSITION, PREPARATION METHOD THEREFOR, ELECTRONIC INK MICROCAPSULES AND ELECTROPHORETIC DISPLAY DEVICE

摘要

A nanometer pigment composition, a preparation method therefor, electronic ink microcapsules and an electrophoretic display device. The nanometer pigment composition comprises a pigment. A surfactant is grafted to the surface of the pigment and is a silane coupling agent or an anionic surfactant. Because of the surfactant on the surface of the pigment, the fluidity, the dispersibility and the stability of the nanometer pigment composition are improved.
