This work has focused on a red electronic ink microcapsules with a core of pigment phthalocyanine red F5R modified with octadecylamine and a wall of UF materials. The electronic ink is suspended in tetra-chloroethyl-ene using span-80 as emulsifier, exhibiting a good dispersibility and stability. Situ polymerization is realized by various conditions including reaction temperature, acidification time, stirring speed and curing condition, etc Optical microscopy and electrical measurements have been applied for microcapsule morphology and performance evaluation. The ink microcapsules with an average diameter of 120μm exhibit a good electrophoretic response.
