Abstract
A laminate body includes a base material, a film-like or a membrane-like undercoat layer that is formed in at least a portion of the outer surface of the base material, and an atomic layer deposition film that is formed on a surface opposite to a surface coming into contact with the base material among both surfaces of the undercoat layer in the thickness direction thereof. At least a portion of precursors of the atomic layer deposition film bind to the undercoat layer, and the atomic layer deposition film is formed into a membrane shape covering the undercoat layer.
Claims13
A laminate body, comprising:
- a base material;
- a membrane-like or film-like undercoat layer that is formed on at least one portion of the outer surface of the base material;
- and
- an atomic layer deposition film that is formed on the surface of the undercoat layer which is opposite to the surface of the undercoat layer coming into contact with the base material, wherein
- at least a portion of precursors of the atomic layer deposition film bind to the undercoat layer,
- the atomic layer deposition film is formed into a membrane shape that covers the undercoat layer,
- the undercoat layer includes a binder and an inorganic substance,
- at least a portion of precursors of the atomic layer deposition film binds to the inorganic substance included in the undercoat layer,
- at least a portion of the inorganic substance is exposed on the surface opposite to the surface coming into contact with the base material, and
- the precursors of the atomic layer deposition film bind to the outer surface of the exposed inorganic substance.
A method of manufacturing a laminate body, comprising:
- loading a base material;
- forming a membrane-like or film-like undercoat layer comprising a binder and an inorganic substance in at least a portion of the outer surface of the base material loaded by the loading;
- removing a portion of the binder exposed on the surface of the undercoat layer which is opposite to the surface of the undercoat layer coming into contact with the base material so as to expose at least a portion of the inorganic substance on the surface of the undercoat layer;
- and
- forming the atomic layer deposition film on the surface of the undercoat layer which is opposite to the surface of the undercoat layer coming into contact with the base material such that the precursors of the atomic layer deposition film bind to the inorganic substance exposed by the removing the portion of the binder.
A method of manufacturing a laminate body, comprising:
- loading a base material;
- forming a membrane-like or film-like undercoat layer comprising an organic polymer in at least a portion of the outer surface of the base material loaded by the loading;
- performing surface treatment on a portion of the surface of the undercoat layer which is opposite to the surface of the undercoat layer coming into contact with the base material so as to increase a density of polar functional groups of the organic polymer as compared to a baseline density of the polar functional groups without the surface treatment, the surface treatment being performed on the undercoat layer by oxygen plasma etching where an output power of the oxygen plasma etching is 300 watts and a treatment time of the oxygen plasma etching is 180 seconds;
- and
- forming the atomic layer deposition film on the surface of the undercoat layer which is opposite to the surface of the undercoat layer coming into contact with the base material such that the precursors of the atomic layer deposition film bind to the polar functional groups of the organic polymer that have increased the density.
