Thermal Control of Structural Color Based on Inorganic Nanosheets

Abstract

Recently, we found that inorganic nanosheets in water self-assemble to form a liquid-crystalline lamellar structure with an ultra-large periodicity by controlling the interactions between the nanosheets. The resultant dispersion exhibits a vivid structural color that can be tuned by thermal stimuli. In this presentation, we will report a new type of structural color with double reflection peaks by applying a temperature gradient to the nanosheet dispersion.
