Highly efficient energy-saving windows with high solar modulation properties (Δ) are the everlasting pursuit of research for industrial applications in the smart window field. Hybridization is an effective means of improving both Δ and luminous transmittance (). In this paper, hybrid thermochromic films were synthesized using tungsten-doped VO nanoparticles (NPs) and starch derivatives. Thermoresponsive 2-hydroxy-3-butoxypropyl starch (HBPS) was prepared with a low critical solution temperature (LCST) varying from 32 to 21 °C by the substitution of reactive groups. The hybrid film was obtained by dispersing W-doped VO NPs in HBPS hydrogels, which exhibiting remarkable solar modulation property (Δ = 34.3%) with a high average luminous transmittance ( = 53.9%).
具有高太阳调制特性（Δ）的高效节能窗户是智能窗领域工业应用研究的永恒追求。杂化是提高Δ和透光率（）的有效手段。本文采用钨掺杂VO纳米颗粒（NPs）和淀粉衍生物合成了杂化热致变色薄膜。通过反应基团的取代制备了低临界溶解温度（LCST）在32至21℃之间变化的热响应性2-羟基-3-丁氧基丙基淀粉（HBPS）。通过将W掺杂的VO NPs分散在HBPS水凝胶中获得杂化薄膜，其具有显著的太阳调制特性（Δ = 34.3%）和高平均透光率（ = 53.9%）。
