In developing flexible display system such as e-Paper based on electrophoresis of tiny particles, full color realization has been most challenging to date. Large amount of endeavors has been poured to develop the color e-Paper system. Here we prepared an electrophoretic ink material, based on various pigment particles coated with hydrophobic polymer layer, which directly donate temporary charge instead of permanent charge via molecular charge control additives. Those color hybrid nanoparticles of large charge density and long terms stability are capable of migrating between electrodes under electric field, and presenting bistability without aggregation. The encapsulation of pigment-embedded hybrid nanoparticles has been conducted via various encapsulation methods to prepare robust and transparent microcapsules, and the performance has been examined in terms of electromobility and bistability in a low dielectric medium and explored the appeal of electrophoretic imaging. |
