As a typical thermochromic material, VO 2 coatings can be applied to smart windows by modulating the transmission of near infrared (NIR) light via phase transition. However, the inherent undesirable luminous transmittance ( T lum ) and solar modulation efficiency (Δ T sol ) of pure VO 2 impede its practical application. In order to solve this problem, the porous VO 2 based composite film was prepared by magnetron sputtering and subsequent acid solution process with Zn 2 V 2 O 7 particles used as a sacrificial template to create pores, which showed excellent T lum (72.1%) and enhanced Δ T sol (10.7%) compared with pure VO 2 film. It was demonstrated that the porous structure of the film caused by acid solution process could improve the T lum obviously and the isolated VO 2 nanoparticles presented strong localized surface plasmon resonance (LSPR) effects to enhance the Δ T sol . Therefore, this method will provide a facile way to prepare VO 2 based films with excellent thermochromic performance and thus promote the application of the VO 2 based films in smart windows. |
