Abstract

Abstract : Graphite oxide is an interesting candidate for electronic applications; therefore, important efforts are dedicated to both large‐scaled and low‐cost graphite oxide production as an intermediate in graphene production. At the same time, research efforts are aimed at identifying the role of defects in the magneto‐electrical properties of platelets for electronic applications. In this paper, we present a new low‐cost fabrication process to obtain graphite oxide platelets of high crystal and thermoelectrical quality. The graphite oxide platelet samples were first obtained from bamboo pyroligneous acid (GO‐BPA) by thermal decomposition method using a pyrolysis system for different carbonization temperatures from 673 to 973 K. The GO‐BPA samples were characterized by using Raman, FTIR, XRD, and TEM techniques, whose results suggest that increased carbonization temperature increases graphite conversion, boundary defects, desorption of some organic compounds and phonon response, respectively. Finally, we discuss potential applications of the GO‐BPA samples involving phonon response that would benefit from a fully scaled technology, advanced electronic sensors, and devices.
