Surface-modified pigment particles for electrophoretic display and electrophoretic display device
The invention provides pigment particles and an organic modification layer formed on a surface of the pigment particles; the organic modification layer is a surfactant layer or a polymer material layer formed on the surface of the pigment particles; an organic matter content over the specific surface area Wsurf of the pigment particles is in a range of 0.1-2% g/m2. The surface-modified pigment particles provided by the invention have good stability, and the electrophoretic display prepared by using the surface-modified pigment particles of the invention has good optical performance.
