Researchers from two universities in Omsk (OmSTU, Dostoevsky Omsk State University) have developed electrochromic polymer films that can be used in the creation of "smart" glass.
According to Professor Alexander Fisyuk of OmSTU, such films have a wide range of applications: from dimming windows in a "smart" home and glass protecting museum exhibits from light, to "smart" glasses and mirrors. The main feature of electrochromic devices is the production of films of any color.
These polymer films have high contrast in the infrared spectrum - up to 84%. This parameter is important in the development of glass with reduced heat loss. Consequently, the use of polymer films will help reduce heating costs, OmSTU explained.
Currently, when using electrochromic materials, the color change time is up to 12 seconds, while the so-called "rainbow effect" is maintained at the edges of the glass. The invention of Omsk scientists changes color in 1.5 seconds, due to the speed the "rainbow effect" is leveled. Scientists from OmSTU and Omsk State University plan to begin developing a prototype based on their film.
