CARBON SPHERE OF PARTICLE-UNIFORMITY AND SMALL SIZE-DISTRIBUTION AND THE USE THEREOF

摘要

A method of improving the properties and properties of black particles using electron species using carbon spheres, which are carbon nanoparticles having a uniform particle shape and a narrow size distribution, is proposed. The carbon sphere of the present invention has excellent dispersibility and bistability in polymer coating and can be used as pigment particles for an electrophoretic electronic paper display device having a high charge through charge control. Therefore, it is possible to constitute a consistent screen when the electronic paper is driven by replacing carbon black, which is black particles included in the conventional electronic paper, and to improve the uniformity of the reaction speed and to help maintain the screen.
