The PNIPAM-co-allylamine/dichloromethane mixture is incubated for a period of time at a given temperature, forming the colloidal crystal material. The colloidal crystals can be stabilized by diffusing a glutaric dialdehyde solution into the colloidal crystal material. The concentration of polymer matrix microgels can determine the orientation of random or columnar crystals.
专利号:US-12429715-B2 优先权日:2018-11-06 标 题:Synthesis and application of light management with thermochromic hydrogel microparticles 发明人:FANG NICHOLAS; LI XINHAO; LIU CHANG; FENG SHIEN-PING 权利人:MASSACHUSETTS INST TECHNOLOGY; UNIV OF HONG KONG 摘要: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 Ëœ32° 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. A high luminous transmittance of 87.2% is accomplished. The pNIPAm-AEMA device demonstrates tunable scattering with excellent stability and scalability, which may find application in a broader field of light management beyond energy-saving smart windows.
