Abstract:
Graphite Oxide (GO) was synthesized using the Improved Hummer’s Method. After the
successful synthesis of GO, it was characterized and its dielectric properties were
investigated. The change of dielectric behavior of GO upon exposure to chlorine gas (Cl2)
was studied. The obtained data were then analyzed to determine the mechanism by which the
dielectric properties change. It was established that the gas physisorption is a two step
process of which, one process has linear dependence with time while the other process
modeled according to the Langmuir isotherm model. Finally the FT-IR spectra of the material
before and after being exposed to Cl2 gas were compared to understand the changes made to
the material.
