Preparation and characterization of colored electronic ink nanoparticles by high temperature-assisted dyeing for electrophoretic displays.
The charged polymer nanoparticles of poly(methyl methacrylate-co-ethylene glycol dimethacrylate) were prepared by emulsifier-free emulsion copolymerization and aminolysis. Coloring on the nanoparticles was achieved by high temperature-assisted disperse dyeing. In the presence of a charge control and stabilizing agent, the colored PMMA nanoparticles showed the electrophoretic mobility because of the amine groups on their surfaces. The morphology and material characteristics of the colored polymeric nanospheres were also investigated.
