Intelligent control of solar transmission through windows promises to reduce energy consumption for thermal comfort in buildings. However, the ability of current smart windows to regulate solar gain based on tunable extinction of phase-change materials is not optimum. A thin-film thermochromic device based on tunable light scattering of hydrogel microparticles of prescribed diameters is reported. In the study, poly (N-isopropylacrylamide)-2-Aminoethylmethacrylate hydrochloride (pNIPAm-AEMA) microparticles are synthesized, with low phase transition temperature ˜32° C. Notably, the average size of pNIPAm-AEMA particles can vary from 1388 nm at 25° C. to 546 nm at 35° C., leading to unprecedented infrared transmittance modulation of 75.6%, in agreement with the numerical simulation based on Mie theory.
