• Vanadium dioxide/titanium nitride (VO2/TiN) smart coatings are prepared by hybridizing thermochromic VO2 with plasmonic TiN nanoparticles. The VO2/TiN coatings can control infrared (IR) radiation dynamically in accordance with the ambient temperature and illumination intensity. It blocks IR light under strong illumination at 28 °C but is IR transparent under weak irradiation conditions or at a low temperature of 20 °C. The VO2/TiN coatings exhibit a good integral visible transmittance of up to 51% and excellent IR switching efficiency of 48% at 2000 nm. These unique advantages make VO2/TiN promising as smart energy‐saving windows. Thermochromic vanadium oxide (VO2) film is coated on titanium nitrate (TiN) plasmonic nanoparticles to fabricate a hybrid VO2/TiN smart coating. This novel coating can intelligently control the infrared (IR) radiation under room‐temperature conditions by reflecting the IR radiation at a high temperature while allowing most of the radiation to go through at a low temperature.
