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

Abstract

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 (Δ<italic>T</italic>_sol) of 25.5% and high average luminance transmittance (<italic>T</italic>_lum) of 70.7% were achieved.
