Abstract
Nanofluids, which are suspensions of nanoparticles in base fluids, have gained significant attention in recent years due to their enhanced thermal and electrical properties. In particular, propylene glycol-water nanofluids have been extensively investigated for their electrical properties. The primary goal of this study is to evaluate the electrical characteristics of nanofluids containing graphene powder distributed in propylene glycol-water. Compositions containing 100:0, 75:25, as well as 50:50 of Propylene Glycol as well as Water were created, along with other nano fluids. Both types of base fluids were infused with graphene at quantities of 0.25 as well as 0.5 percent, respectively. The assessment of electrical characteristics in nanofluids includes the analysis of parameters like breakdown voltage, permittivity, resistivity, and electrical conductivity. With the increase in the diameter there is an increase in the value of resistivity with the dispersion of graphene nano powder whereas breakdown voltage, permittivity and electrical conductivity have been decreased with the increase in the diameter. Overall with the dispersion of graphene in nano powder the electrical properties have been enhanced. Furthermore, it discusses the underlying mechanisms and provides insights into potential applications of propylene glycol-water nanofluids in electrical and electronic systems.
