“…Smart windows are categorized based on different stimuli, including heat, [9–13] electricity, [14–20] light, [21–26] and humidity [27,28] . Thermochromic smart windows are highly competitive among different response modes due to their unique features such as low cost, simple structure, passivity, and reasonable stimulus‐response [29,30] . Currently, various thermal response materials have been successfully applied, including vanadium dioxide (VO 2 ), [31–37] hydrogels (poly‐N isopropyl acrylamide (PNIPAm), [38,39] hydroxypropyl cellulose (HPC), [40,41] N‐vinyl caprolactam (PNVCL), [42] and other types [9,32,43–47] .…”
