Kazuki Tajima (Research Scientist) and his co-workers at the Energy Control Thin Film Group (Leader: Kazuki Yoshimura), the Materials Research Institute for Sustainable Development (Director: Mamoru Nakamura) of the National Institute of Advanced Industrial Science and Technology (AIST) (President: Hiroyuki Yoshikawa) have developed a flexible switchable mirror film that can be electrically switched between reflective and transparent states.
The newly developed all-solid-state switchable mirror film operates as an electrochromic system using electricity. Because it uses only electricity and does not require any special control system, the initial costs for the introduction of the switchable mirror film are low. The film is made entirely of solid materials, and thus offers an easy handling, etc.
The film can also be used in privacy glass or security equipment because, in its reflective state, it prevents the inside of a building or vehicle from being seen from the outside. A technique has been developed for laminating these switchable layers on a film, and a 100-micrometer-thick electrochromic switchable mirror film has been produced. The new product is more easily produced, has a better economic efficiency, is more easily recyclable, and is more easy handling than existing switchable mirror films formed on glass. As the switchable mirror film can be stuck on already built window glass, the range of applications of this film was expanded dramatically.
