Design of ultra-stretchable, highly adhesive and self-healable hydrogels via tannic acid-enabled dynamic interactions

Abstract

Hydrogels have emerged as a landmark soft material for a wide range of applications such as in biomedical devices, soft robotics, artificial electronic skins, and Internet of Things (IoT). To...

Black phosphorus nanosheets-enabled DNA hydrogel integrating 3D-printed scaffold for promoting vascularized bone regeneration

“…Fortunately, hydrogels with dynamic properties can adapt to the environment, coordinate with the tissue regeneration process, and self-heal after damage [ [21] , [22] , [23] ]. The reversible network can be realized by dynamic covalent bonds or noncovalent interactions [ 24 , 25 ].…”

Dual crosslinking hydrogels with tunable injectability and stability for bone repair

“…26,27 Previous studies have confirmed that hydrogen bonding interactions can be generated between TA and PEG, as well as between TA and carboxyl groups. 28,29 Therefore, in this system, first, the combination of TA and PAsp–PEG–PAsp depending on hydrogen bonds results in the formation of the first crosslinking process. The resulting gels are obviously shear-thinning and self-healing due to weak and reversible hydrogen bonding interactions.…”

Facile synthesis of ultralight S-doped Co3O4 microflowers@reduced graphene oxide aerogels with defect and interface engineering for broadband electromagnetic wave absorption

“…The ice crystals formed during the freezing process largely determine the porous structure of S-Co 3 O 4 @RGO aerogels, which are synthesized by replacing the liquid component of a hydrogel with a gas component through a freeze-drying process. 44,45…”
