Thermochromic material responds to solar spectrum differently at the stimulus of heat which makes it attractive in the energy saving smart windows application. The most studied inorganic VO2 has the intrinsic problems of low luminous transmission (Tlum) and low solar modulation (ΔTsol the transmission difference between high and low temperatures).1 Numerous efforts such as employing dopings, 1,2 nanoparticle-based composites,1,3 and nano-porous structuring 1,4 have been widely studied. Our group have developed five new approaches to tackle this veritable challenge, namely, biomimetic nanostructuring including moth eye, 5 photonic structure,6 grided structures7,8 tunable plasmonic structures9 and organic and hybrid structures.10,11 In addition, an active control has also been applied to thermochromic material to generate a new electro-thermochromics materials.12
