ABSTRACT
An ideal energy‐saving smart window can not only provide a comfortable indoor temperature to avoid energy consumption of air‐conditioning but also require low for the material itself. However, current studies on windows either need extra electric and heat switching or still face some challenges such as high durability. Herein, supramolecular nanocomposite hydrogel film is prepared by integrating ethylene glycol‐modified pillar[5]arene ( EGP5 ) antimony‐tin oxide (ATO) nanoparticles. Owing thermo‐responsiveness plasmonic heating induced near‐infrared (NIR) absorption ATO, obtained exhibits an outstanding photo‐thermochromic effect, which results in excellent sunlight‐induced solar modulation. Meanwhile, possesses repeatability durability based dynamicity reversibility ‐based host–guest interaction. Therefore, this further applicable fabrication investigation regulating temperature. The result demonstrates that preferentially trigger its effect achieve cool more life.
