Abstract

The present invention provides an adhered structure in which members of the same or different materials are adhered to each other with a high adhesive strength and a method for producing the adhered structure. The adhered structure of the present invention comprises a first solid member, a second solid member, and an adhesive member. The first solid member and the second solid member are adhered to each other through the adhesive member. The adhesive member contains a polymer. The polymer is chemically bonded to the first solid member and the second solid member.

First claim

The invention claimed is:

1. An adhered structure comprising a first solid member, a second solid member, and an adhesive member,
the first solid member and the second solid member being adhered to each other through the adhesive member,
the adhesive member comprising a polymer,
the polymer being chemically bonded to the first solid member and the second solid member, and
the polymer comprising a polyrotaxane.

2. The adhered structure according to claim 1 , wherein the polymer comprises a (meth)acrylic polymer compound.

3. The adhered structure according to claim 2 , wherein the first solid member and the second solid member are each made of a material selected from the group consisting of metals, resins, glasses, and inorganic materials, and the material of the first solid member and the material of the second solid member are the same or different.

4. The adhered structure according to claim 2 , wherein one or both of the first solid member and the second solid member have a plasma-treated portion or portions on a surface or surfaces in contact with the adhesive member.

5. The adhered structure according to claim 1 , wherein the first solid member and the second solid member are each made of a material selected from the group consisting of metals, resins, glasses, and inorganic materials, and the material of the first solid member and the material of the second solid member are the same or different.

6. The adhered structure according to claim 1 , wherein one or both of the first solid member and the second solid member have a plasma-treated portion or portions on a surface or surfaces in contact with the adhesive member.

7. An adhered structure comprising a first solid member, a second solid member, and an adhesive member,
the first solid member and the second solid member being adhered to each other through the adhesive member,
the adhesive member comprising a polymer,
the polymer being chemically bonded to the first solid member and the second solid member, and
wherein the polymer has a structure crosslinked by host-guest interactions.

8. The adhered structure according to claim 7 , wherein the first solid member and the second solid member are each made of a material selected from the group consisting of metals, resins, glasses, and inorganic materials, and the material of the first solid member and the material of the second solid member are the same or different.

9. The adhered structure according to claim 7 , wherein the first solid member and the second solid member are each made of a material selected from the group consisting of metals, resins, glasses, and inorganic materials, and the material of the first solid member and the material of the second solid member are the same or different.

10. The adhered structure according to claim 7 , wherein one or both of the first solid member and the second solid member have a plasma-treated portion or portions on a surface or surfaces in contact with the adhesive member.

11. A method for producing an adhered structure comprising a first solid member, a second solid member, and an adhesive member, the method comprising an adhesion step of subjecting at least one polymerizable monomer to a polymerization reaction to form a polymer-containing adhesive member and to thereby adhere the first solid member and the second solid member to each other through the adhesive member, wherein the first solid member and the second solid member have polymerizable reactive groups on surfaces,
the polymer is chemically bonded to the reactive groups,
wherein the method comprises a surface treatment step B of subjecting both of the first solid member and the second solid member to at least one treatment selected from the group consisting of plasma irradiation, ozonization, base treatment, and acid treatment before the adhesion step, and
wherein the polymerizable monomer comprises a polymerizable polyrotaxane.

12. The method according to claim 11 , wherein the first solid member and the second solid member are each made of a material selected from the group consisting of metals, resins, glasses, and inorganic materials, and the material of the first solid member and the material of the second solid member are the same or different.

13. The method according to claim 11 , comprising a surface treatment step A of treating one or both of the first solid member and the second solid member with a silane coupling agent before the adhesion step.

14. The method according to claim 11 , wherein the reactive groups are radically polymerizable.

15. A method for producing an adhered structure comprising a first solid member, a second solid member, and an adhesive member, the method comprising an adhesion step of subjecting at least one polymerizable monomer to a polymerization reaction to form a polymer-containing adhesive member and to thereby adhere the first solid member and the second solid member to each other through the adhesive member, wherein the first solid member and the second solid member have polymerizable reactive groups on surfaces,
