Resumo: The challenge for nanotechnology application in automotive lubrication is the difficulty in dispersing the nanoparticles in lubricating oils. Some factors have a direct influence on the dispersion of particles, such as size and shape, which are controlled by the chosen synthesis method. In addition, the use of covers and dispersant agents aid the dispersion of nanoparticles in lubricating oils. In this work studied the effect of different amount of energy given during the synthesis of nanoparticles in microwaves, in order to observe its influence on the dispersion size and shape of nanoparticles. They were covered with oleic acid, as well disperse in toluene, improving nanoparticle dispersion. The dispersion in of nanoparticles in oil was observed by physical characteristic, spectroscopy in the visible ultraviolet (UV/VIS) and micrographs (MO). The results showed that the synthesis with higher amount of energy generated a smaller particle size and better dispersion in oil. However the nanoparticle shape is not influenced by energy amount. The use of Oleic acid and toluene improved the dispersion of the nanoparticles in the lubricant oil as observed in the results of UV/ VIS by biggest interparticle distance
