Preparation of Microencapsulated Electrophoretic Ink used for an Electronic Paper

摘要

An electrophoretic display (EPID) based on the movement of particles in an insulating liquid is well known to be one of the technology utilized for the electric paper and has been actively investigated in the past few years. Micro-encapsulation of non-aqueous dispersion containing with white and black particles is reported in this paper. The melamine resin was used for wall material of micro-capsule. The optimization of the preparation condition of the micro-encapsulation was done. The EPID using the micro-encapsulated electrophoretic ink displays black and white solid image in the response to an external voltage.
