PARTICLE EXTERNAL ADDITIVE FOR E-PAPER FOR COMPOSITE SURFACE TREATMENT USING CARBONBLACK,SIO2 AND PARTICLE FOR E-PAPER TREATED COMPOSITE SURFACE USING THEREOF

摘要

PURPOSE: A particle external additive for electronic paper for composite surface treatment using carbon black and SiO2 and a particle for electronic paper thereof are provided to combine carbon black with silicon dioxide, thereby placing the carbon black combined with the silicon dioxide on a surface of a particle. CONSTITUTION: A plurality of carbon black particles(20) are added externally to a bare particle. A plurality of silicon dioxide particles(40) are added externally to the carbon black particles. The carbon black particles are evenly distributed on a surface of the bare particle. The silicon dioxide particles are evenly distributed on a surface of the carbon black particles. The silicon dioxide particles are not close to the bare particle and are placed between the carbon black particles.
