Ultrasonic probing in the modulation mode of ultrasonic waves (work/rest) was used for more efficient graphite oxidation-exfoliation. It is shown that the 4/2 s mode of ultrasonic modulation is the most effective in terms of probe material's low corrosion, maintaining optimum synthesis temperature, and achieving the best characteristics of the resulting product.
