Publication number: 20150357494Abstract: A gas permeation barrier structure comprises a rigid or flexible substrate, an oxide or nitride layer deposited thereon by atomic layer deposition (ALD), and a polymeric clear coat. The presence of the polymeric clear coat permits the barrier structure to maintain resistance to permeation of gases including oxygen and water vapor longer than would a structure in which the ALD layer is directly exposed to atmosphere.Type: ApplicationFiled: January 30, 2014Publication date: December 10, 2015Inventors: David M. Dean, Carl Brent Douglas, Nicholas J. Glassmaker
