Abstract

It is important to examine the factors that determine the properties of graphene. Various factors affect the properties of graphene nanosheets that can revolutionize the use of graphene. One such factor is ultrasonic waves, which have significant effects on graphene properties. In this research, we studied the effect of ultrasonic waves with different power levels (35, 50, 360, and 420 W) on four graphene samples. in this research all the samples fabricated by electrochemical exfoliation. In this method, ammonium sulfate nonorganic salt was used for producing solution and used electrodes PT and graphite where +10 volt was applied to the electrodes Ultrasonic waves are used to homogenize the electrolyte for samples. And samples were analyzed using scanning electron microscope (SEM) imaging and Fourier transform infrared spectroscopy (FTIR) spectroscopy to determine their structure and electrical properties. The I-V curves of the samples were measured after spraying the glass substrate. Then, FTIR spectra and I-V characteristics were studied. Our results showed that with increasing ultrasonic power, FTIR spectra did not change, however conductivity of grown graphene increases.
