Ultra-high barriers for encapsulation of flexible displays and lighting devices

A roll-to-roll manufactured ultra-high permeation barrier film based on a multilayer stack of sputtered oxide layers and ORMOCER® interlayers is presented. The reproducible large-area water vapor transmission rate is less than 8·10−5 g/(m2d) at ambient condition. The film has been evaluated as substrate for and encapsulation of flexible organic electronic devices.
