PB35 Tunable color display device with selective reflection of a hydroxypropyl cellulose aqueous solution

Abstract

Hydroxypropyl cellulose (HPC) aqueous solution has a property of selective reflection. Because the selective reflection wavelength of HPC depends on a concentration of inorganic salts, the color of the HPC solution can be changed by an applied electric field that can move ions. In this study, we are trying to make a color tunable display device of HPC, which can change color freely by applied voltage.
