摘要

In this study, inorganic multilayer thin-film encapsulation is adopted for the first time to protect an organic layer from moisture and oxygen. Inorganic multilayer thin-film encapsulation is deposited onto poly(ethylene terephthalate) (PET) using an electron beam and sputtering. The SiON/SiO_2 and parylene layer show the most suitable properties. Under these conditions, the water vapor transmission rate (WVTR) for PET can be reduced from a level of 0.57 gm~(-2) day~(-1) (bare substrate) to 1 x 10~(-5) g m~(-2) day~(-1) after the application of a SiON and SiO_2 layer. These results indicate that PET/parylene/ SiO_2/SiON barrier coatings have high potential for flexible organic light-emitting diode (OLED) applications.
