| Abstract: | The blue electronic ink microcapsules,which have a core of pigment phthalocynine blue BGS modified with octadcylamine and a wall of UF materials,have been studied.The electronic ink was suspended in tetra-chloroethylene using span-80 as emulsifier,and a good dispersibility and stability was exhibited.Situ polymerization is realized by the various conditions including prepolymer preparation,reaction temperature,acidition time,stirring speed and curing condition,etc.FTIR,micro-photography and electrical measurements were applied for particle measurement,structure analysis and performance evaluation.The ink microcapsules exhibited a sphere shape with a smooth surface and a good electrophoretic response.The average diameter of it was about 100 μm. |
