Temperature influence in the electrical conductivity of graphite oxide platelets*

Graphite oxide platelets from bamboo pyroligneous acid (GO-BPA) synthesized by using the double thermal decomposition (DTD) method at 973 K as carbonization temperature, exhibit temperature influence in the electrical conductivity like a semiconductor material. Samples were characterized by using Raman, FTIR, XRD, XPS, HR-TEM and I-V curves (two and four-points at temperatures of 20 to 300 K) techniques. Electrical measurements suggest that increased temperature increases electrical conductivity like a semiconductor material. Conduction mechanism was described mainly by 3D-variable range hopping.
