COLORED ELECTORNIC INK NANOPARTICLES FOR ELECTRONIC DISPLAYS AND PREPARATION THEREOF

摘要

Colored electronic ink nanoparticles for electronic displays are provided to facilitate the control of the amount dispersed and be uniformly dispersed because the shape of the particles and the number of aggregate are uniform. Colored electronic ink nanoparticles for electronic displays are prepared by the steps of: polymerizing styrene, divinylbenzene, and vinylacetate by a non-emulsion polymerization method using ammonium persulfate as an initiator to prepare cross-linked poly(styrene/divinylbenzene/vinylacetate) nanoparticles; dispersing the poly(styrene/divinylbenzene/vinylacetate) nanoparticles in methanol, thereto adding sodium hydroxide, and stirring and reacting the admixture for 4-6 hours to prepare poly(styrene/divinylbenzene/vinylalcohol) nanoparticles having hydroxyl groups; and dyeing the poly(styrene/divinylbenzene/vinylalcohol) nanoparticles with a disperse dye.
