In order to apply organic color pigments into the electrophoretic display technique, they were encapsulated with copolymer, poly(acrylamide-co-methyl methacrylate) using dispersion polymerization of acrylamide and methyl methacrylate in the presence of red colored organic pigment in this study. Chemical structure of the product was characterized via an FT-IR spectroscopy to confirm the polymer coating. Surface charge transfer after the coating process was also analyzed by measuring zeta potential of the fabricated particles in distilled water. Electrophoretic response of the particles in the low dielectric suspending medium was analyzed using an electrophoresis light scattering measurement. Effect of charge control agent on the zeta potential of the suspended particles in low dielectric solution was further investigated.
