Temperature and environment effects on the graphene oxide reduction via electrical conductivity studies
Original language description
In this article, we report a study carried out to understand how changes in environment and temperature, in which the graphene oxide (GO) film reduction occurs, alter the electrical properties of the resulting films. In fact, it is possible to improve the GO reduction efficiency by choosing suitable environment and temperature. To this purpose, three different environments (high vacuum, air and nitrogen) and three dissimilar temperatures (177 degrees C, 300 degrees C and 600 degrees C) have been chosen, as suggested by differential scanning calorimetry (DSC) measurements. Among the investigated thermally reduced graphene oxide films, the ones treated at 600 degrees C in nitrogen have shown to possess higher electrical conductivity. Such an enhanced electrical conductivity can be attributed to reduction of oxygen functional groups and restoration of sp(2)carbon network, as confirmed by Raman spectra.
