Abstract
Official abstract text for this publication.
A stimulus-responsive gel material includes: a first polymer containing an OH group and having a network structure; a second polymer having a phenylboronic acid structure; fine particles having an average particle diameter of 10 nm or more and 1000 nm or less; and a solvent, wherein a polymer chain of the second polymer penetrates into the network of the first polymer.
First claim
Opening claim text (preview).
What is claimed is: 1. A stimulus-responsive gel material, comprising: a mixture including: a first polymer containing an OH group and having a network structure; a second polymer having a phenylboronic acid structure; fine particles having an average particle diameter of 10 nm or more and 1000 nm or less; and a solvent, wherein the first and second polymers each have a cross-linked structure; the first polymer contains N-hydroxyethylacrylamide as a constituent component; and a polymer chain of the second polymer penetrates into the network of the first polymer. 2. The stimulus-responsive gel material according to claim 1 , wherein the material is capable of being put into the following states: a first state in which the OH group of the first polymer and the phenylboronic acid structure of the second polymer are bonded to each other; and a second state in which the bond between the OH group of the first polymer and the phenylboronic acid structure of the second polymer is dissociated, and the wavelength of a reflected light from the material is different between the first state and the second state. 3. The stimulus-responsive gel material according to claim 1 , wherein the second polymer has a network structure. 4. The stimulus-responsive gel material according to claim 1 , wherein the material is put into the second state by reacting the phenylboronic acid structure of the second polymer and lactic acid with each other. 5. The stimulus-responsive gel material according to claim 1 , wherein the second polymer contains acrylamidephenylboronic acid as a constituent component. 6. The stimulus-responsive gel material according to claim 1 , wherein when the content of the first polymer is denoted by X1 (mass %) and the content of the second polymer is denoted by X2 (mass %), X1 and X2 satisfy the following relationship: 0.2≦X2/X1≦8. 7. The stimulus-responsive gel material according to claim 1 , wherein water is contained as the solvent.
