“…The optical modulation range is close to the value (14.9%) of TiO 2 nanoporous film obtained by spin-coating using polyethylene glycol as pore-forming agent. 57 This means small amounts of the incorporation of GO can improve optical modulation properties of pure TiO 2 film, which can be attributed to loose and porous nanostructure of TiO 2 /RGO nanocomposite film.…”

A novel and scalable method combining surfactant template and electrophoresis deposition was used to prepare mesoporous titanium dioxide/reduced graphene oxide (TiO 2 /RGO) nanocomposite film with the assistance of sodium dodecyl benzene sulfonate using tetrabutyl titanate and graphene oxide (GO) as raw material. The electrochromic mechanism of TiO 2 /RGO nanocomposite film was investigated by XPS technique. The TiO 2 /RGO nanocomposite film showed that TiO 2 nanocrystals can be anchored on the surface of RGO via chemical bonding such as Ti−O−C and Ti−C. The TiO 2 /RGO nanocomposite film exhibited shorter coloration/bleaching response times (3.9 s for coloration and 6.6 s for bleaching), higher coloration efficiency (34.9 cm 2 C −1 ) and better coloration/bleaching cycle stability compared with pure TiO 2 film. The electrochromic mechanism of TiO 2 /RGO nanocomposite film was accorded with valence transition model, and an island-bridge model was proposed to interpret the enhancement mechanism of electrochromic performance. This enhancement is mainly due to a larger specific surface area, higher electrical conductivity and better structural stability in TiO 2 /RGO nanocomposite film, which facilitates faster transport of Li + ions and electrons, and longer coloration/bleaching cycle life. This work provides an effective approach and inspiration to improve the electrochromic performance of transition metal oxides, as well as explore other high-performance electrochromic materials.
