Abstract

The toner type paper-like display (PLD) has been developed with two polymer particles having opposite polarity which is composed of polymer, colorant and external additives (nano-sized silica). Nano-sized silica with triboelectric charge was used for the charge control agent (CCA) and influenced on the electrostatic properties of the silica-coated polymer particles. The PLD cell using silica-coated particles (200 seconds) had shown a good white appearance and low driving voltage. The result could be explained in terms of the surface morphology and the cohesiveness depending on the silica coating time.
