Fujifilm develops film that offers world's highest level of moisture barrier property with transparency

Fujifilm Corporation has developed "transparent super high barrier film" – a film that offers the world's highest level of moisture barrier property with transparency. The film is essential for flexible electronic devices, currently under research and development in fields including organic electroluminescence (EL) displays and solar cells. The "transparent super high barrier film, "developed by Fujifilm, offers an advanced level of moisture barrier performance at 10-6[g/(m²•d)], through combining knowledge of organic materials, accumulated through past R&D of photographic film and flat-panel display materials, with the film formation technology that enables precision control of film properties and thickness to prevent defects that could affect barrier performance. The establishment of the Roll-to-Roll film formation method also provides positive outlook for volume production. It enables the formation of a barrier layer on various types of base film, including transparent and flexible PET (Polyethylene Terephthalate) and PEN (Polyethylene Naphthalate), and therefore may be applied to a wide range of fields as high-performance film, required in flexible electronic devices. Flexible organic EL displays, electronic papers, organic EL lightings and thin film solar cells are expected to become next-generation electronic devices. These devices require flexible, transparent, and thin/lightweight high-performance films as key component to replace existing glass and metal, which cannot be easily made thinner or lighter. Yet, high-performance films, when used as key components, must demonstrate an extremely high level of barrier property to block external moisture, which could deteriorate electronic devices' component performance and damage their durability. Fujifilm will actively seek opportunities to introduce our technologies, and will actively start distribution of samples to facilitate the development of their applications in various fields.
