Abstract

The present invention relates to a method for manufacturing an external additive for an electronic paper particle using titanium dioxide, and to the external additive for the electronic particle using the titanium dioxide manufactured thereby, and comprises: an amino group provision step of adding hydrochloric acid to a first solvent, to which the titanium dioxide is added, reacting same, and manufacturing the titanium dioxide having the amino group; and a charge provision step of adding ammonia water to a second solvent, to which the titanium dioxide having the amino group is added, and reacting same. According to the present invention, the external additive can be more quantitatively and uniformly adsorbed to the particle by using a solution adsorption method, and a chemical combination can significantly enhance durability. Furthermore, by synthesizing the amino group to the titanium dioxide, clumping between the particles can be prevented and advantageously and significantly increases particle mobility.
