Definitions
- the invention relates to a structure of a barrier layer, in particular to a structure of a barrier layer capable of maintaining long-lasting barrier properties and high barrier performance against the external environment.
- the plastic material is less resistant to the external environment than the glass, in order to replace the traditional glass material with the aforementioned plastic or thin metal materials, the problem that the industry faces the most need to solve is to improve the environment from the outside world, especially water vapor and gas (In particular, the barrier properties of oxygen.
- the prior art Gas barrier film is a common and widely adopted solution.
- the existing technologies are based on the consideration of the multi-layer film and the selection of materials that can exert the gas barrier effect, as the direction and goal of technology development. And it is worth noting that, regardless of the manufacturing method or the solution that can be provided by the material, the prior art is realized by the concept of solid multi-layer film.
- One of the objects of the present invention is to provide a barrier layer structure capable of covering at least a portion of an object to block the contact of moisture or gas from the external environment with the object.
- Another object of the present invention is to provide a barrier layer structure which has ductility, flexibility and bendability, can cover any shape and appearance of an object, and provides a barrier against the external environment, especially for moisture or gas ( Especially oxygen) the barrier properties to be maintained.

- the liquid material has only a dynamic free volume, but no structural defects of the solid matter.
- the interfaces at the interface between the first gel layer and the second gel layer are non-porous interfaces. If the external environment of water vapor or gas (especially oxygen) wants to penetrate the second layer of the second layer, it must first be absorbed by the second layer, diffused in the second layer, and then from the second layer. It is possible to contact the object by separating it from the interface between the object, the substrate layer or other overlapping barriers.

Therefore, the second gel layer can fill a portion of the static pores of the first gel layer close to the interface. Therefore, when the external environment of water vapor or gas (especially oxygen) passes through the path of the static pores in the first layer, it will also form a high concentration gradient near the barrier interface, which is more detrimental to water vapor or gas. The diffusion phenomenon required to enter the second gel layer is generated, and thus the moisture or gas of the external environment is more difficult to enter the second gel layer.
- the second gel layer may further comprise a plurality of polar molecules.
- the polar molecule may then comprise a hydrogen bonding molecule, a chelating functional molecule or a charged ion. Therefore, the effect of the barrier can be further improved.
- the adsorbed moisture or gas (especially oxygen) is not easily separated from the interface, which is not conducive to the diffusion of moisture or gas (especially oxygen) and its absorption by the second layer of the layer, that is, its diffusion phenomenon is thus greatly reduced.
