Abstract: To obtain excellent electrophoretic particles for E-paper, a number of techniques have been developed to modify the surfaces of particles for high surface charge density or decrease the particle densities, including mechanical, chemical and physicochemical methods. In this paper, these methods according to the applications in the preparations of white particles, black particles and chromatic particles have been separately summarized. Besides, the advantages or shortcomings of these methods utilized in electrophoretic particles preparations have been compared and elaborated. In particular, several different but valuable routes to prepare the white, black and chromatic electrophoretic particles based on the researches of our group are reported. At the end, the prospect of development and applications of electrophoretic particles is illustrated.

Key words: E-paper, electrophoretic display, electrophoretic particle, pigment, coating, surface modification
