Photocrosslinked Chitosan Hydrogels Reinforced with Chitosan‐Derived Nano‐Graphene Oxide

Macromolecular Chemistry and Physics, 2019
AbstractChitosan and chitosan‐derived nano‐graphene oxide carbon dots are successfully methacrylated and utilized for the fabrication of photocurable hydrogels. The addition of the nano‐graphene oxide (nGO) does not significantly delay the polymer network build‐up, but significantly reduces the storage modulus of the crosslinked network, with important
