▎ 摘 要
To obtain graphene, we propose to use organic reagents and pure graphite exposed to ultrasound. Toluene, benzene, kerosene, and hydrogen peroxide are used as organic reagents. Results of experimental investigations of graphene in the systems under consideration are presented. Graphene structures have been obtained due to chemical interaction of these organic solvents with graphite. This led to the destruction of weak carbon bonds between graphite planes. We have found that the ultrasonic field provides a more effective destruction of the van der Waals bonds between graphite planes. The results of our investigation show that the use of the abovelisted organic solvents, unlike other methods using acids and alkali solutions, provides a more efficient method of obtaining graphene structures. Results of investigations of graphene structures by the method of electron paramagnetic resonance spectroscopy are presented and discussed.
