Abstract

Supported by the diverse chemistry of the catechol group, pH-responsive, mussel-inspired hydrogels has drawn considerable attention due to the presence of reversible catecholato–metal bonds, which incorporates self-healing properties. Through oxidation, catechols also participates in covalent cross-linking and as these impacts the abovementioned properties, it is of great interest to control the degree of which these are present; i.e. controlling the degree of catechol oxidation.
Until now, the catechols participating in the two cross-linking types have been the same. This way the actual ratio between the two types cannot be either predefined or controlled, as it is determined by the oxidation rate within the hydrogel.
Here, we report hydrogels in which the catechols participating in reversible (oxidation resistant catechol) and irreversible (classical catechol) cross-links are separated, enabling one to predefine the ratio of the two by altering the composition.
