PARTICLE EXTERNAL ADDITIVE FOR E-PAPER FOR COMPOSITE SURFACE TREATMENT USING TiO2,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 a composite surface treatment using titanium dioxide and silicon dioxide, comprising: bare particles; A plurality of titanium dioxide particles attached to the bare particles; And a plurality of silicon dioxide particles externally attached to the titanium dioxide particles. According to the present invention, unlike the prior art, by mixing titanium dioxide and silicon dioxide having an amino group 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 the voids of the external additives are eliminated, there is an advantage that can maximize the effect of improving the aggregation and fluidity between particles due to the amino group.
