Poor, non-tunable mechanical properties as well as finite shape memory performance pose a barrier to shape memory hydrogels to realize practical applications. Here, a new shape memory hydrogel with tunable mechanical properties and multi-shape memory effect was presented. Three programmable reversible systems including PBA-diol ester bonds, AAc-Fe3+ and coil-helix
transition of agar were applied to memorize temporary shapes and endow the hydrogel with
outstanding multi-shape memory functionalities. Moreover, through changing the crosslinking
densities, the mechanical properties of the as-prepared hydrogel can be adjusted.
