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

The present invention relates to a particle external additive for electronic paper for the composite surface treatment using carbon black and silicon dioxide, comprising: bare particles; A plurality of carbon black particles attached to the bare particles; And a plurality of silicon dioxide particles externally attached to the carbon black particles. According to the present invention, unlike the prior art, by mixing the carbon black having an amino group and silicon dioxide and crying on the particle surface, it is possible to suppress the aggregation between particles and to significantly improve the fluidity, and unlike the conventional external additive, the particle surface Since no voids in the external additives are eliminated, there is an advantage that can maximize the effect of agglomeration and fluidity between particles due to the amino group.
