3D-printable self-healing and mechanically reinforced hydrogels with host–guest non-covalent interactions integrated into covalently linked networks

Materials Horizons 2019 Volume 6, Pages 733-742

Natural polymer hydrogels are one of the best biomaterials for soft tissue repair because of their excellent biocompatibility, biodegradability and low immune rejection. However, they lack mechanical strength matching that of natural tissue and desired functionality (e.g., self-healing and 3D-printability). To solve these problems, we developed a host–guest supramolecule (HGSM) with three arms covalently crosslinked with a natural polymer to construct a novel hydrogel with non-covalent bonds integrated into a covalently crosslinked network. This unique structure enabled the hydrogel to exhibit improved mechanical properties and show both self-healing and 3D printing capabilities. The three-armed HGSM was first prepared via efficient…
