Abstract
Official abstract text for this publication.
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 21 a 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A self-restoring macromolecular material comprising a crosslinked structure that is formed by crosslinking a polymer containing at least a polyrotaxane molecule, the polyrotaxane molecule comprising a cyclic molecule and a linear molecule passing through an opening of the cyclic molecule, the crosslinked structure being crosslinked between the cyclic molecule of the polyrotaxane molecule and a polymer molecule other than the polyrotaxane molecule via a bond between a host group and a guest group, wherein the bond between the host group and the guest group comprises a non-covalent bond, and the host group and the guest group form an inclusion complex. 2. The self-restoring macromolecular material according to claim 1 , wherein the polymer molecule further comprises a polyrotaxane molecule other than said polyrotaxane molecule. 3. The macromolecular material according to claim 1 , wherein the host group is a cyclodextrin. 4. The macromolecular material according to claim 1 , wherein the cyclic molecule is a cyclodextrin. 5. The macromolecular material according to claim 2 , wherein the host group is a cyclodextrin. 6. The macromolecular material according to claim 2 , wherein the cyclic molecule is a cyclodextrin. 7. The macromolecular material according to claim 3 , wherein the cyclic molecule is a cyclodextrin.
