Abstract:
The Raman spectra and the temperature dependence of the electrical resistance of graphene oxide in the process of continuous heating and cooling in an argon atmosphere in the temperature range of $300$–$550$ K are studied. The $D$ and $G$ bands in the Raman spectra are described, and their nature is determined. A decrease in the $D$-band intensity after thermal treatment is related to a decrease in the concentration of oxygen-containing groups. This leads to a decrease in electrical resistance with increasing temperature. It is found that the resistance is independent of temperature in the range of $300$–$370$ K, which testifies to a thermal stability of graphene oxide resistance.
