Effect of Ultrasonic Waves on Morphology and Electrical Treatment of Graphene

It is important to examine the factors that determine the properties of graphene. various factors can affect the properties of graphene nano sheets. understanding such factors can revolutionize the use of graphene. one such factor is ultrasonic waves, which have significant effects on graphene physical and chemical properties such as (electronic and optical). in this research, we studied the effect of ultrasonic waves with different power levels (35, 50, 360, and 420 w) on four graphene samples for 10 minute. so all the samples were fabricated by electrochemical exfoliation. in this method, ammonium sulfate nonorganic salt was used for producing solution and electrodes pt and graphite were used, where +10 volt was applied to the electrodes. ultrasonic waves were used to homogenize the electrolyte for the samples. the samples were analyzed using scanning electron microscope (sem) imaging and fourier transform infrared spectroscopy (ftir) spectroscopy. the i-v curves of the samples were measured after spraying on the glass substrate. then, ftir spectra and i-v characteristics were studied. our results showed t he increase of ultrasonic power could cause some changes in the intensity of spectral ftir and the conductivity of graphene sheets.
