Seed-assisted Hydrothermal Method: Hydrated Tungsten Trioxide Nanosheet Film

Hydrated tungsten trioxide nanosheet film is an ideal electrochromic electrode, which can be prepared by seed-assisted hydrothermal method. And the prepared electrochromic film has the advantages of large light modulation range, high coloring efficiency, short electrochromic response time and good cycle stability, which means that such film has good heat insulation performance.

In addition, experts say that the hydrated WO3 nanosheet electrochromic film is structurally stable with a certain mechanical strength. Also, such film has good adhesion to the substrate, which can withstand the lattice stress and volume change caused by the injection and extraction of ions and electrons. In other words, the film shows good cycle stability. Experts also mentioned that the presence of urea enables the hydrated WO3 film prepared by the seed-assisted hydrothermal method to have a stronger ion storage capacity. For the hydrated WO3 nanosheet film prepared by the urea-induced seed-assisted hydrothermal method, what allows the prepared film to exhibit good electrochromic properties? The porous structure formed by the staggered arrangement of the nanosheets, the more ion permeation channels of the hydrated WO3, and strong ion storage capacity of materials caused by urea.
