Abstract
A method for preparing an adhesive, said method comprising—mixing chitosan and tannic acid in an aqueous solution, and adjusting the pH value of the resulting mixture to a pH that induces the formation of a polymer-rich phase and a polymer-poor phase, preferably in a pH range of from 4.5 to 6, such as from 5 to 5.5 to obtain a polymer-rich phase and a polymer-poor phase; and—isolating the polymer-rich phase to obtain said adhesive. Described is also an adhesive obtainable from said method and uses thereof.
