Fabrication and Properties of Electrophoretic Display Thin Film for Electronic Paper

The electrophoretic display thin film (EPDTF) was fabricated using gelatin/gum arabic microcapsules as display materials. The influential factors of preparing the film, which included transmittance, surface tension, viscosity, the preservative rate, and the surface morphology, were investigated. After being sandwiched with the electrodes, the reflective properties of the EPDTF were characterized by fiber-optic spectrometer. Moreover, the display property was also investigated. The results revealed that the EPDTF can be prepared with flatten surface morphology, good flexibility, fine reflective properties, and high intrinsic bistability at the binder concentration of 1.0 wt%. Furthermore, a static image can be displayed clearly by applying a voltage pulse.
