Temperature-responsive hydrogel with ultra-large solar modulation and high luminous transmission for “smart window” applications

Thermally responsive hydrogel with a transition temperature of ~32 °C was for the first time studied as a novel candidate in thermochromic application. Unprecedented solar modulating ability (ΔT_sol) of 25.5% and high average luminance transmittance (T_lum) of 70.7% were achieved.
