Com o progresso das investigações sobre nanomateriais, cientistas de diversas partes do mundo têm direcionado suas pesquisas para explorar a utilização desses materiais em uma ampla gama de áreas, como microeletrônica, medicina e tribologia. É amplamente reconhecido que os nanomateriais à base de carbono, quando adicionados a graxas, apresentam um grande potencial para diminuir o atrito nas partes móveis de máquinas, o que contribui para aumentar a eficiência e a durabilidade dos equipamentos. Neste estudo, utilizou-se óxido de grafeno (GO) com uma concentração inicial de 13,6 mg/mL misturado a óleo Spindle para analisar a dispersão, a homogeneidade, o desempenho tribológico e a eficácia deste material como aditivo em graxas para aplicabilidade automobilística. Após a preparação da dispersão, observou-se visualmente que a solução apresentava alta viscosidade. Foram realizados testes para avaliar a viscosidade e também testes tribológicos, a fim de verificar a qualidade do material e sua viabilidade para ser considerado como uma possível graxa.

With the advancement of nanomaterial research, scientists around the world have focused their efforts on exploring the use of these materials in a wide range of fields, including microelectronics, medicine, and tribology. It is widely recognized that carbon-based nanomaterials, when added to greases, have significant potential to reduce friction in moving parts of machinery, thus improving efficiency and durability. In this study, graphene oxide (GO) was used with an initial concentration of 13.6 mg/mL mixed with Spindle oil to assess the dispersion, homogeneity, tribological performance, and effectiveness of this material as an additive in greases for automotive applications. After preparing the dispersion, a high viscosity of the solution was visually observed. Tests were conducted to evaluate the viscosity and also tribological tests to ensure the quality of the material and its feasibility as a potential grease.
