Originální abstrakt

The purpose of this study is to insight more thoroughly into the structural properties of graphene oxide (GO) in particular of the type generated by Hummer's method in relation with graphite precursor originating from different sources. The systematic study using elemental analysis (EA), thermogravimetric analysis (TGA), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) was performed to verify microstructure changes of GO microstructure. The results confirmed the considerable influence of both the character of graphite source and the isolation procedure of GO by lyophilisation. Further, maintaining of GO in a form of aqueous colloidal dispersion is crucial to preserve its unique properties. SEM results revealed the occurrence of associated GO blocks formed from identically oriented planes.
