Abstract: The authors report the design of a prototype smart window based on the phenomenon of the thermally induced aggregation of triblock copolymer poly (ethylene oxide)–poly (propylene oxide)–poly (ethylene oxide) (EPE). Fluorescein isothiocyanate was used to label EPE and study aggregation phenomenon at different temperatures. The cloud point could be tuned by mixing EPE with sodium dodecyl sulfate (SDS) and varying the concentration of the latter. The light transmittance at different temperatures was studied as a function of SDS concentration.

Thermochromic properties and low emissivity of ZnO:Al/VO2 double-layered films with a lowered phase transition temperature
Litao Kang,Yanfeng Gao,Hongjie Luo,Jun Wang,B.L. Zhu,Zongtao Zhang,Jing Du,Minoru Kanehira,Yuzhi Zhang +8 more
TL;DR: In this paper, the optical and semiconductor-metal transition properties of ZnO:Al/VO 2 /substrate double-layered films were studied, and the transition temperatures for VO 2 shifted to lower temperatures after the deposition process, which was due to the formation of surface nonstoichiometry.
