Abstract: The present invention provides a joined body with no risk of detachment from the joining surface without using an adhesive, and a method for producing the joined body. The present invention also provides a reversible joined body that enables control of joining and dissociation, and a method for producing the reversible joined body. In the joined body, a chemical bond is formed between two or more same or different solid-state materials at their contact interfaces by a chemical reaction.

Abstract: Provided are a host-group-containing polymerizable monomer usable as a starting material for producing a macromolecular material with a high degree of freedom in material design, and excellent toughness and strength; a macromolecular material produced using the host-group-containing polymerizable monomer; and a method for producing the macromolecular material. The host-group-containing polymerizable monomer according to the present invention is a host-group-containing polymerizable monomer, and the host group is a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative. The cyclodextrin derivative has such a structure that the hydrogen atom of at least one hydroxy group of a cyclodextrin is replaced with a group selected from the group consisting of a hydrocarbon group, an acyl group, and —CONHR wherein R represents a methyl group or an ethyl group.

Abstract: Provided is a self-restoring macromolecular material that not only has excellent stress relaxation but that can also be easily restored to its original state, even when damaged or severed. Also provided is a method for producing the self-restoring macromolecular material. The self-restoring macromolecular material contains a crosslinked structure that is formed by crosslinking a polymer containing at least a polyrotaxane molecule. The polyrotaxane molecule is formed so as to include a cyclic molecule 21 and a linear molecule that passes through an opening 21a of the cyclic molecule. The crosslinked structure 1 is crosslinked via a reversible bond between the cyclic molecule of the polyrotaxane molecule and a polymer molecule other than the polyrotaxane molecule.
