Abstract
A process for making a barrier film having a substrate, a base polymer layer applied to the substrate, an oxide layer applied to the base polymer layer, and a top coat polymer layer applied to the oxide layer is provided. An optional inorganic layer can be applied over the top coat polymer layer. The top coat polymer layer is formed by vapor depositing and curing cyclic aza-silane and acrylate monomer. The use of a silane co-deposited with an acrylate to form the top coat layer of the barrier films provide for enhanced resistance to moisture and improved peel strength adhesion of the top coat layer to the underlying barrier stack layers.
