Preparation and Properties of Graphene Sheets Coupled with Magnetic Nanoparticles |
| 초록 |
The pioneering experiments in graphite exfoliated-graphene sheets by Geim et al established its potential to surpass and substitute many best performing electronic and photonic alternatives. The chemical and electronic properties of graphene can be modulated by effective coupling of this material with other nanomaterials. A successful functionalization strategy would be one that would leave the graphene surface unperturbed and preserves its much valued electronic properties. We present the design and application of pyrene based ligands which couple nanomaterials to graphene surface through non-covalent π-π stacking. We have successfully developed novel synthetic routes of the pyrene-dopamine systems tethered to γ-Fe2O3. Iron oxide intercalated graphene composites are highly desirable materials for energy storage. The distance between nanoscale components in hybrid materials play a crucial role in governing their electronic transport properties. |
