Preparation and Characterization of Graphene Based Hybrid Materials
 Hrubý, Jakub ; Novák, Jiří (oponent) ; Neugebauer, Petr (vedoucí práce)
Graphene with metal complexes could provide novel approaches in graphene-based hybrid materials and molecular magnetism. Both topics are highly innovative as such, however, there is a little research into possibilities of mixing them. Samples were prepared by a liquid-phase sonication of graphite which resulted in the exfoliation of graphene. Subsequently, various metal complexes were deposited onto a graphene-covered substrate by modiied Langmuir–Schaefer method. An essential step was to determine the material’s properties. Consequently, properties of new hybrid materials were characterised by high frequency electron paramagnetic resonance (HFEPR), scanning electron microscopy (SEM), Raman spectroscopy and four-point probe resistance measurements. Herein, the results conirmed our presumption that it is possible to mix exfoliated graphene with potential molecular magnets in order to gain novel magnetic and electronic properties which could be possibly utilised in the next generation of detectors and electronics.
