Tungsten trioxide film for electrochromic and manufacturing method thereof

摘要

The present invention relates to a tungsten trioxide thin film for an electrochromic device and a manufacturing method thereof, and more particularly, to a thin film of tungsten trioxide having a honeycomb structure with regularly arranged nano grooves, And to provide an electrochromic device having durability. According to various embodiments of the present invention, a tungsten trioxide thin film having a honeycomb structure can be manufactured by arranging the nano grooves regularly. In addition, the tungsten trioxide thin film exhibits remarkable effects in improving the coloring speed and durability when applied to an electrochromic device, and thus can be widely applied to various fields such as functional windows and displays.
