摘要：
An electrophoretic dispersion with at least two particle species is proposed in which a minimal number (and concentration) of free compounds is present in solution. All chemicals needed to color and stabilize the pigment particles are preferably covalently attached to or within the particles. This enhances the robustness of the system and minimizes the conductivity of the dispersion so that the driving voltage for an electrophoretic display is reduced.
