摘要：Highly efficient energy-saving windows with high solar modulation properties (Delta T-sol) are the everlasting pursuit of research for industrial applications in the smart window field. Hybridization is an effective means of improving both Delta T-sol and luminous transmittance (T-lum). In this paper, hybrid thermochromic films were synthesized using tungsten-doped VO2 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 degrees C by the substitution of reactive groups. The hybrid film was obtained by dispersing W-doped VO2 NPs in HBPS hydrogels, which exhibiting remarkable solar modulation property (Delta T-sol = 34.3%) with a high average luminous transmittance (T-lum,T- average = 53.9%).
