Abstract
Official abstract text for this publication.
A coacervate including a catechol-substituted anionic polymer; an adhesive including same; and a method for producing the coacervate are described. More specifically, a coacervate formed by mixing a catechol derivative of a mussel adhesive protein and a catechol-substituted anionic polymer; an adhesive including the coacervate; and a method for producing a coacervate are described. The method includes a step of obtaining a catechol-substituted anionic polymer through catechol substitution of an anionic polymer, and a step of mixing the catechol-substituted anionic polymer and a catechol derivative of a mussel adhesive protein.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coacervate comprising: a mixture of: a catechol derivative of a modified mussel adhesive protein in which a tyrosine residue is modified as a catechol derivative, and a catechol-substituted hyaluronic acid as anionic polymer, wherein a substitution degree of the hyaluronic acid is 10% to 52%. 2. The coacervate of claim 1 , wherein the catechol derivative of the mussel adhesive protein comprises 10% to 100% of a total number of tyrosine residues the mussel adhesive protein is a catechol derivative substitution. 3. The coacervate of claim 1 , wherein the catechol derivative is at least one selected from the group consisting of 3,4-dihydroxyphenylalanine (DOPA), DOPA o-quinone, 2,4,5-trihydroxyphenylalanine (TOPA), TOPA quinone and a derivative thereof. 4. The coacervate of claim 1 , wherein a molecular weight of the hyaluronic acid is 1 kDa to 5000 kDa. 5. The coacervate of claim 1 , wherein the substitution degree is 30% to 50%. 6. The coacervate of claim 1 , wherein the substitution degree is 35% to 50%. 7. An adhesive comprising the coacervate claim 1 .
