Combined Cyclic-Static Bending Effect on the Encapsulation Properties of a Barrier Thin Film for Flexible Organic Optoelectronic Devices

Abstract:

Water vapor transmission rate (WVTR) of a barrier film is evaluated after combined cyclic-static bending. Results show that cyclic bending combined with a static bending deteriorates the barrier performance to a greater extent, compared with pure cyclic bending. For a severe bending radius of 2.5 mm, WVTR is increased at the beginning of combined cyclic-static bending. There is a little effect of static bending on WVTR for a short hold time. However, for a longer period of static hold-time, the contribution of static bending to deterioration in the performance of barrier thin film is visible.
