Abstract
Disclosed are a method for manufacturing a thermochromic film, a thermochromic film manufactured using the same, and a smart window including the thermochromic film. The method for manufacturing the thermochromic film includes a first step of forming a metal thin-film on a substrate; and a second step including: heating a first solution containing a vanadium dioxide precursor to perform hydrothermal synthesis of vanadium dioxide; dispersing the synthesized vanadium dioxide in a solvent to prepare ink; and applying the ink onto a surface of the metal thin-film formed on the substrate to coat vanadium dioxide on the metal thin-film.

A method for manufacturing a thermochromic film for a smart window, the method comprising:
- a first step of forming a metal thin-film on a substrate;
- and
- a second step including:
- heating a first solution containing a vanadium dioxide precursor to perform hydrothermal synthesis of vanadium dioxide;
- dispersing the synthesized vanadium dioxide in a solvent to prepare ink;
- and
- applying the ink onto a surface of the metal thin-film formed on the substrate to coat vanadium dioxide on the metal thin-film,
- wherein the metal thin-film layer reflects visible light.
A thermochromic film for a smart window, the thermochromic film comprising:
- a substrate;
- a metal thin-film layer formed on the substrate;
- and
- a vanadium dioxide thin-film formed on the metal thin-film layer,
- wherein the substrate includes polyethylene terephthalate (PET),
- wherein the metal thin-film layer reflects visible light, and
- wherein the metal thin-film layer includes at least one metal selected from silver, aluminum, platinum, palladium, or gold.
