pH-dependent relaxation of mussel inspired hydrogels containing covalent and coordination bonds. Samples were formed at pH 3 and then equilibrated to the pH values indicated before testing in compression. Samples were strained to 20 %, and the stress was monitored for 100 s. A1 represents the steady-state stress.
