摘要

Electronic ink, electronic paper and a preparation method of the electronic ink. The electronic ink comprises display particles, an electrophoresis base solution, and microcapsule prepolymer, wherein the display particles are an inorganic mixture of a white pigment and a particle size of the display particles is 20-50nm. The inorganic mixture of the white pigment is obtained by mixing one or multiple of zinc oxide, zinc sulfide and lithopone with boric oxide, lithium oxide and zirconium oxide. The electronic ink can improve image sharpness of a display device.
