Graphene and graphene derivatives can also contribute the introduction of new functions to hydrogels, such as mechanical strength, biological activities, and stabilities, via multiple molecular interactions with hydrophilic polymers. In particular, my research has focused on the creation of graphene-incorporated hydrogels which have dispersed reduced graphene flakes in hydrogel matrices. The resultant hydrogels, depending on the contents of the graphene flakes and matrix types, can show diverse interesting characteristics, including adsorption of small molecules, electrical conductance, an anti-oxidizing ability, and strong interaction with macromolecules. With these specific characteristics originated from grapehene/hydrogel composites, various functions have been demonstrated, including the improved molecular adsorption, 3 dimensional cell printing bioinks, muscle-mimicking hydrogels scaffolds, and stem cell delivery vehicles. |
