Abstract
Multilayer barrier films and methods of making the films are provided. The films include a smooth layer and a barrier layer directly disposed on the smooth layer. In some cases, the smooth layer includes a thiol-ene material as a polymeric matrix material. In some cases, the films have a sandwich structure of barrier layer/smooth layer/substrate/smooth layer/barrier layer.
