Abstract
A biliquid material includes an emulsion having a continuous liquid phase, a dispersed liquid phase, and a surface-stabilizing material, wherein: the dispersed liquid phase is immiscible with the continuous liquid phase; the dispersed liquid phase is in the form of a plurality of droplets in the continuous liquid phase; the surface-stabilizing material is soluble in at least one of the continuous liquid phase and the dispersed liquid phase and preferentially adsorbs at the surfaces of the plurality of droplets, wherein the surface-stabilizing material imparts a repulsive interaction between the plurality of droplets that inhibits coalescence of the plurality of droplets; and the biliquid material has a structurally-colored droplets structure, wherein the structurally-colored droplets structure yields one or more structural colors when illuminated with broad-spectrum light wherein the one or more structural colors arise from diffraction of the broad-spectrum light by the plurality of droplets.
