Abstract

This study places SiC nanoparticles into deionized water and uses NaOH and H2SO4 to produce alkaline and acid nanofluids, respectively. A Cu electrode was then inserted into the SiC nanofluid with different voltages activated to observe particle absorption at the electrode and to investigate the electrochemical properties of SiC nanofluid under the influence of voltage, as well as the aggregation and precipitation of particles. In addition, the three-polar method is used to produce anodic polarization curves of the acid and alkaline solutions with the SiC particles to determine the electric potentials of oxidation reduction of the acid and alkaline nanofluids, respectively. The overall purpose of this research was to investigate the electrical properties of SiC nanoparticles in SiC nanofluids of varying pH values.
