The present invention relates to a method for surface-treating an electronic paper particle using a titanium dioxide additive, and to the electronic paper particle using the titanium dioxide additive manufactured thereby, and comprises: a reaction preparation step of adding a bare particle to a second solvent into which a titanium dioxide having an amino group is added, and then dispersing same to manufacture a reaction preparation solution; and a particle surface treatment step of adding hydrochloric acid and glutaraldehyde to the reaction preparation solution and reacting same. According to the present invention, by using a solution adsorption method instead of an existing method, the external additive can be more quantitatively and uniformly adsorbed to the particle, and a chemical combination can significantly enhance durability. Also, the durability and mobility of the particles can be significantly enhanced by reacting the hydrochloric acid, the glutaraldehyde, the titanium dioxide having the amino group, and the particles at an optimum proportion according to the solution adsorption method. |
