Highly Improved Dielectric and Thermal Performance of Polyalphaolefin Oil-Based Fluids Using MgO Nanoparticles

Polyalphaolefin (PAO) oil is widely used as a dielectric liquid due to its outstanding strength, high flash point, good oxidation resistance, and stability. The dispersion of MgO nanoparticles in PAO yields nanofluids with many properties superior base oils. This study clarifies the influence on (breakdown voltage, volume resistivity, relative permittivity) heat transfer PAO/MgO nanofluids. Changes concentration size modification surfactants change thermal performance Using raw material prepare fluid obtains product higher strength conductivity than those using PAO. results show that nanofluid-based has potential be applied soft coating protect electronic equipment industries.
