Abstract

Wax-based electrophoretic rewritable media have been investigated since they potentially have good preservation characteristics. Reducing the thickness of rewritable media is critical for reducing the writing/erasing energy of wax-based rewritable media. The present study investigates the effect of rewritable media thickness. Samples of with dye concentrations of 0, 0.03, and, 0.07 wt. % and TiO2 concentrations of 2.5, 5, and 10 wt. % with respect to wax were prepared with media thicknesses of 0.05, 0.1, and 0.2 mm and their rewritable characteristics were evaluated. The Kubelka-Munk equation was applied to investigate the dependence of the reflection of the dyed side on the dye and TiO2 concentrations and the absorption coefficient of the dye was estimated. It was found that a TiO2 concentration of 5 wt. % and a dye concentration of 0.07 wt. % give suitable display characteristics for cells with thicknesses of 0.1-0.2 mm. A preliminary rewrite experiment was performed on an enlarged dot cell.
