Synthesis of Charged Hybrid Particles via Dispersion Polymerization in Nonpolar Media for Color Electrophoretic Display Application

Abstract : Direct synthesis of charged hybrid particles in nonpolar media has not been widely described in the literature but can lead to many applications such as electrophoretic displays. In this work, we propose a way to synthesize charged hybrid particles within the electrophoretic medium (Toluene or Isopar G) in the presence or not of additives (Charge Control Agent, CCA). The particles synthesis was performed by Nitroxide-mediated Radical Polymerization (NMRP) via dispersion polymerization in aliphatic hydrocarbon solvents leading to stable chargeable particles with a good size control. Hybrid particles are successfully charged by reaction with functional monomers or addition of CCA to obtain electrophoretic particles. The performance of a dual-color red/white ink in a display was demonstrated with a test-cell. (C) 2016 Wiley Periodicals, Inc.
