Solar control glazing is the promising development for energy saving for energy saving buildings. Thermally responsive hydrogels or polymers have been mainly used to construct thermotropic glazing, in which the switching mechanism is dominated by the temperature-induced aggregation of the materials in the solvent above the lower critical solution temperature (LCST). Because of the sharp phase transition, traditional smart windows are inability to control the transmittance in a stepwise manner on demand. Here, we prepared gradient copolymers that each copolymer has a different monomer composition, thereby showing different thermal behavior depending on the composition. We demonstrated that the obtained copolymer exhibits a volume phase transition over a wide temperature range. |
