Synthesis and characterization of graphene oxide (GO) have allowed developing
different mechanisms of control to improve its mechanical, optical and
structural properties. The temperature control in the synthesis process
(Hummers modified method) is an important factor that defines the quality of
the microstructure, chemical exfoliation, the functionalization with different
organic groups and some relevant changes in the crystal structure. A study was
conducted by controlling temperature rise which originates exothermic process
reaction with H 2 O & H 2 SO 4 . Which allowed observing the influence of the
released heat in the material reaction. The GO was characterized using
techniques XRD, SEM, AFM, EDX, FTIR, which noted the shift of the plane (001) in
7° to 12° (2 theta), a high level of degradation on the material surface, it wich to
leave it exposed to the exothermic process reaction (85°C) and how it was
corrected with the temperature control at 15°C, was analyzed the influence of
surface degradation through images of topology and phase to identify the
change affecting the microstructure of the material, a qualitative analysis was
applied to meet the stoichiometry of the material and the level absorption of
the organic groups present during the process of functionalization.
