A Review of Transparent Barrier Coatings

Presented by B.M.Henrey, University of Oxford

The transparent barrier films presently available on the market all have their strengths and weaknesses. At the same time there is consideration to use more plastic-based materials for different applications, e.g. displays and insulation panels. This situation has stimulated the industry to provide new, more efficient barrier solutions. Some of the innovations go along the following lines: nanocomposite materials; Ormocers®; hybrid PECVD coatings; PML structures; and ‘super sapphire’ sputtered layers. This extended abstract presents an overview of some of the different approaches, outlining the basic principle behind each
barrier technology, its performance and the companies developing and producing the materials.
