Organic optoelectronic devices like organic light-emitting diodes (OLEDs), have attracted considerable attention due to their advantageous characteristics, low manufacturing cost, simple massive and large-area production, flexibility and light weight. However, the polymer which are highly permeable to water vapor due to free volume and low cohesive energy between carbon chains can cause the degradation of electronics. Therefore, effective permeation barrier is essentially needed to prevent the invasion of oxygen and vapor. The encapsulation, a barrier film directly deposited onto an electronic device like OLED, is considered essential for longevity of electronics and fabricated by various methods. In our report, we aimed to prepare thin film encapsulation (TFE) consisting of alternately stacked Al2O3 and hybrid material constituted with Silca/Titania precursor showing excellent water anticorrosion, low-gas permeation, and low-temperature processing and good mechanical characteristics. |
