Abstract
A retrofitted window is disclosed which includes a substantially transparent aerogel film laminated on a glass windowpane, the aerogel film being embedded with randomly dispersed nanoparticles of vanadium dioxide (VO2) core and silicon dioxide (SiO2) shell, wherein the vanadium dioxide (VO2) core transitions between an insulator phase and a metal phase at a predetermined phase-transition temperature, and a volume fraction of the nanoparticles in the aerogel film is approximately between 0.001% and 0.05%.
Claims16
A retrofitted window comprising:
- a glass windowpane;
- and
- an aerogel film embedded with randomly dispersed thermochromatic nanoparticles laminated on the glass windowpane, the chromogenic nanoparticles transitioning between an insulator phase and a metal phase at a predetermined phase-transition temperature,
- wherein the individual thermochromatic nanoparticle has a vanadium dioxide (VO2) core with a diameter between 5 and 50 nm.
