Abstract

In this study, smart glass with the property of auto-adjust transparency was constructed to economize the consumption of energy by screening sunlight irradiation entering a building. Graphene oxide (GO), a photothermal conversion material, when intercalated within a thermotropic hydrogel can effectively convert the photoenergy of sunlight into thermal energy and cause the smart glass to reach an opaque state owing to the increased temperature of the hydrogel heated by solar light, as a result, reducing the incident intensity of solar energy and room temperature. In addition, GO embedded within the thermotropic hydrogel absorbs the colored organic solvent, which provides the smart glass with arbitrary color.
