Abstract
Herein, the benzidine yellow PY14 (background color) and the red metal complex dye (developing particles) are dispersed in a mixed solvent of tetrachloroethylene and xylene without adding a charge control agent to prepare an electrophoresis liquid. The electrophoresis liquid is coated into microcapsules by a complex coacervation method, and the capsule wall material is gelatin and gum arabic. Observe the morphology of the microcapsules, test the reflection density, particle size distribution and test the performance index. Finally, an electrophoretic display principle device was fabricated using indium tin oxide (ITO) conductive glass. The results showed that when the particle size of benzidine yellow was dispersed to 1400 nm and the dispersion time was 120 min, the reflection density was the highest, which was the most favorable for display. The coated microcapsules were made into electronic devices and then electrophoresed structure of the cross-linked sample was better.
