Preparation and properties of two-colour interconversion electronic ink microcapsules

The electronic ink microcapsules containing modified phthalocyanine green G and TiO₂ particles were dispersed in tetrachloroethylene (TCE) and prepared by complex coacervation with Gelatin-Gum acacia as wall materials. The size distribution of the unmodified and modified Phthalocyanine Green G was studied, the dispersing of the modified particles is better than the unmodified. The factors that affected the morphology of the electronic ink microcapsules were also discussed, and the response behavior of electronic ink microcapsules under the DC electric field was also studied. The results showed that the modified Phthalocyanine Green G and TiO₂ nanoparticles have good dispersion behavior and reversibility under the electric field.
