Resumo: | (Introduction) The global demand for energy is constantly growing, requiring the development of efficient systems to ensure sustainable consumption and prevent long-term environmental damage. Carbon-based materials, such as graphene, have been extensively studied due to their environmentally friendly properties, structure, and availability. Squalane is also a component with significant physiological effects in fields like nutrition, pharmacy, and medicine [1]. However, both graphene and squalane are relatively new in the field of nanofluids. While research on thermal conductivity has been prioritized, studies on permittivity and electrical conductivity remain limited. In this study, we analyzed the dielectric permittivity of graphene nanofluid at temperatures of 333.15K and 343.15K. The nanofluid was prepared using squalane as base fluid with a volumetric concentration of 0.75% of graphene nanoparticles, without adding surfactants to avoid interference. |

Carbon-based materials, such as graphene, have been extensively studied due to their environmentally friendly properties, structure, and availability. Squalane is also a component with significant physiological effects in fields like nutrition, pharmacy, and medicine [1]. However, both graphene and squalane are relatively new in the field of nanofluids. While research on thermal conductivity has been prioritized, studies on permittivity and electrical conductivity remain limited. In this study, we analyzed the dielectric permittivity of graphene nanofluid at temperatures of 333.15K and 343.15K.
