In literature, it has been reported that the addition of GO can enhance the storage modulus of alginate-based materials . However, to the best of our knowledge, there is not any publication on the enhancement of E’ for composite hydrogels synthesised with irregular graphene oxide tubes with respect to those with single GO sheets. Therefore, these results confirm our hypothesis of these irregular graphene oxide tubes as better reinforcement agents than single GO sheets in alginate. The possibility of including zinc and strontium in the polymer matrix, which impart antibacterial and healing properties, render these new advanced materials very promising in the biomedical field.
