WO3 Nanotree Array Film

WO3 nanotree array film has excellent electrochromic properties, so it is suitable for the preparation of electrochromic devices such as smart windows for applying to energy saving buildings. Well, do you know how to prepare a WO3 nanotree array film?

Some experts have prepared WO3 nano-tree hierarchical structure array films by hydrothermal oxidation method and hydrothermal synthesis method, respectively. The experts have grown WO3 nanotree array films with hexagonal systems directly on metal tungsten plates by hydrothermal oxidation. And the films are heat-treated below 500 °C to keep the crystal structure unchanged. But why can the tungsten trioxide thin film exhibit excellent electrochromic properties? The hexagonal and triangular ion channels in the WO3 with hexagonal structure are beneficial to the diffusion of ions. And the nano-tree hierarchical structure not only has an open porous surface in full contact with the electrolyte, but is intimately connected to the conductive substrate, thus exhibiting excellent electrochromic properties.
