Hybrid Polymer Film

November 1, 2005

A barrier film for limiting transmission of oxygen and moisture there-through was recently granted a patent. The film comprises a polymer substrate with a first vacuum-formed plasma-treated surface and a vacuum-deposited, first radiation-polymerized acrylate monomer film with first and second surfaces. The first surface of the first polymerized film is located on the first surface of the first plasma-treated surface of the polymer substrate. A first inorganic layer has first and second surfaces. The first inorganic layer is located on the second surface of the first polymerized film. A vacuum-deposited, second radiation-polymerized acrylate monomer film has first and second surfaces. The first surface of the second polymerized film is located on the second surface of the first inorganic layer. The second surface of the second polymerized film is a vacuum-formed plasma-treated surface.
