Abstract

The present invention relates to improved hydrogel materials using water gellants that are comprised of polymer backbones P to which hydrogen bonding 4H-units are covalently attached via a hydrophobic linker L. Optionally, the hydrogel contains additional ingredients or additives. These new reversible hydrogels can easily be fine-tuned in their mechanical performance and function and are especially suitable for biomedical applications.
