Summary: | Water-vapor permeation through metallic barriers deposited on polymer substrates has been an
important technological issue because the performance of the barrier is critical to the reliability of flexible
organic devices. For the development of long-lifetime flexible organic devices, two different sets of samples
were designed and demonstrated from the viewpoint of the water-vapor transmission rate (WVTR). Aluminum
(Al) and polyethylene terephthalate (PET) were chosen for the barrier layer and the polymer substrate,
respectively. Two stacking structures, a single-layer (Al/PET) structure and a double-layer (Al/PET/Al)
structure, were used for the WVTR measurement. For the single-layer structure, the WVTR decreases as the
thickness of the barrier layer increases. Compared to the single-layer sample, the double-layer sample showed
superior WVTR performance (by nearly three times) when the total thickness of the Al barrier was greater
than 100 nm. KCI Citation Count: 3 |
