Acid Solution Processed VO₂-Based Composite Films with Enhanced Thermochromic Properties for Smart Windows.

ABSTRACT: As a typical thermochromic material, VO₂ 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 (ΔT_sol) of pure VO₂ impede its practical application. In order to solve this problem, the porous VO₂ based composite film was prepared by magnetron sputtering and subsequent acid solution process with Zn₂V₂O₇ particles used as a sacrificial template to create pores, which showed excellent T_lum (72.1%) and enhanced ΔT_sol (10.7%) compared with pure VO₂ film. It was demonstrated that the por
