STUDY OF THE PARAMAGNETIC CHARACTERISTICS OF GRAPHENE STRUCTURES OBTAINED IN THE GRAPHITE SYSTEM WITH AROMATIC HYDROCARBONS UNDER THE INFLUENCE OF THE ULTRASOUND FIELD
Keywords:
graphene, aromatic hydrocarbons, ultrasonic method, EPR spectroscopy, paramagnetic centersAbstract
This paper proposes for production of graphene to use the exposure of ultrasound field on the organic reagents and pure graphite. As organic reagents there were used kerosene, hydrogen peroxide, benzene and toluene. The paper presents experimental results of production of graphene in these systems, which is formed by a chemical reaction of these organic solvents with graphite. This leads to the destruction of the weak carbon bonds between the graphite planes. The results of this study indicate that the ultrasound field contributes to more efficient destruction of the van der Waals bonds. The use of enumerated organic solvents in contrast to other methods using acid, alkali solution provides a more efficient way to production of graphene structures. The article presents results of the study of graphene structures by electron paramagnetic resonance spectroscopy, as well as discussion is given.
