INORGANIC/ORGANIC HYBRID NANOLAMINATE BARRIER FILM

摘要

An inorganic/organic hybrid nanolaminate barrier film has a plurality of layers of an inorganic material that alternate with a plurality of layers of an organic material. Such a barrier film can be fabricated using nanocomposite self-assembly techniques based on sol-gel chemistry.

1. A method for making an inorganic/organic hybrid nanolaminate barrier film, comprising:
combining an alkoxide, an alcohol, water dilute HCl and heating the resulting mixture. Introducing a coupling agent to the mixture, introducing a surfactant to the mixture in a quantity sufficient that the initial surfactant concentration is below the critical micelle concentration; adding to the mixture one or more polymer precursors suitable for the formation of a polymer selected from the group of, polyethylene naphthalate (PEN), polyether etherketone (PEEK), polyether sulfone (PES), fluorinated or non-fluorinated styrene polymer precursors, fluorinated or non-fluorinated methyl styrene polymer precursors, fluorinated or non-fluorinated (meth)acrylate polymer precursors, and combinations and/or derivatives of two or more of these precursors; adding a cross-linker agent and an initiator to the mixture; coating a substrate with the mixture; and allowing the alcohol to evaporate so that the sol forms a film having alternating organic and inorganic layers.
