抜粋

A solution of polysilazane (Perhydropolysilazane) was applied to a heat resistant PET substrate, and then irradiated with excimer light at 150 °C to form a gas barrier film. This film primarily consisted of a thin layer of SiO 2 , and had very high gas barrier properties, with a water vapor transmission rate of 0.02 g/m 2 ·day or less (40 °C/90% RH). This gas barrier film has good transparency, film adhesion, surface flatness, and flexibility, and since it has high heat resistance and good gas barrier performance, it is expected to have applications in films for flexible devices.
