Abstract
A new coloured polymer particle was prepared, in which chromophoric groups were introduced onto the surface of the polymer particle for use in electronic ink. The structure, morphology and thermal stability of polymer electrophoretic particles were characterized using FTIR, solid state 13C-NMR, SEM and TGA. Electrophoretic mobility measurements proved that the polymer particles had negative charges in the electrophoretic dispersion medium. Electronic ink microcapsules containing the polymer particles were prepared by coacervation. The polymer particles had a reversible electric response in the microcapsules under a DC electric field.
