VO2/ATO/polymer thermochromic flexible foils for smart window application were prepared by casting VO2 and Sb : SnO2 (ATO) nanoparticles. The foils exhibit an increased solar-heat shielding ability, causing a 20% decrease in solar transmittance at an ATO content of 9%, while retaining an excellent solar modulation ability (6.9%). This development represents a breakthrough for applications to smart windows.
