The discovery of mono-layered graphene, achieved through an experiment by Geim and Novasolev to synthesize a free standing 2D lattice material, garnered global attention due to its outstanding mechanical, electrical and thermal properties. These properties have been exploited in a wide range of applications including super capacitors, actuators, sensors, reinforcing materials in high performance polymer composites and hydrogels, etc. As another approach, researchers have tried integrating carbon nanotubes with graphene to obtain synergetic effects in applications such as actuators, super-capacitors, mechanically compliant films, fuel cell batteries, solar cells, nano-composites and biomedical devices. The synthesis of graphene-CNT (G-CNT) hybrids has thus far been accomplished by a multi-step process. Herein we report a simple microwave-based technique to synthesize graphene-CNT-Fe (G-CNT-Fe) nano-hybrid structures based on ferrocene as the CNT source. Our proposed method is not only fast, but can also yield high volume production of the functionalized nano-hybrids at a fraction of the cost of CVD methods. Furthermore, the obtained hybrids are magnetically active and can be used in a wide range of applications including shape memory artificial muscles and biomedical applications. |
