  • A thin barrier film that acts like a glass: A printable and UV‐densified barrier film; Potential uses in packaging and devices，2023.03

    Professor Yoshiyuki Suzuri and his colleagues at Yamagata University's Innovation Center for Organic Electronics have been developing a less expensive alternative barrier with equivalent performance using printing and coating processes. In their study, they succeeded in fabricating a dense inorganic film in just two minutes at room temperature. The dissolvable polysilazane with Si‐N backbone was densified by irradiation of vacuum‐ultraviolet light with a wavelength of 172 nanometers (one billionth of a meter). This solution‐processed barrier resulted in a water vapor transmission rate of only 4.8 × 10−5 grams per square meter per day, demonstrating glass‐like performance and breaking the previous record by more than one order of magnitude. It marks the world's highest performance for a printed water vapor barrier. The film's optical transparency and flexibility make it versatile for use in various applications.
