Organic/inorganic multi-layered gas barrier film
The present invention employs the totally printable process to fabricate an organic/inorganic multi-layered laminate gas barrier film. Such totally printable process is simple with lower costs. Moreover, through the pattern design, the adhesion between the organic and inorganic layers is improved.
1. A multi-layered gas barrier laminate film, comprising a flexible substrate, a plurality of organic layers disposed over the flexible substrate, a plurality of organic/inorganic hybrid layers and a plurality of inorganic layers disposed over the flexible substrate, wherein the plurality of organic layers, the plurality of organic/inorganic hybrid layers and the plurality of inorganic layers are stacked in a sequence of one organic layer, one organic/inorganic hybrid layer and one inorganic layer, each one of the plurality of organic layers has a pattern with openings, one of the plurality of organic/inorganic hybrid layers fills up the openings of the each one of the plurality of organic layers and fully covers a top surface of the each one of the plurality of organic layers and the plurality of organic/inorganic hybrid layers and the plurality of inorganic layers are interconnected with one another.
2. The multi-layered gas barrier laminate film of claim 1 , wherein the pattern of each one of the plurality of organic layers is different from that of another one of the plurality of organic layers that is most adjacent thereto.
3. The multi-layered gas barrier laminate film of claim 1 , wherein the pattern of each one of the plurality of organic layers is arranged off-set to that of another one of the plurality of organic layers that is most adjacent thereto.
4. The multi-layered gas barrier laminate film of claim 1 , wherein a material of the plurality of organic layers is a macromolecule or a polymer material.
5.
