The mechanism of oil viscosity reduction with the addition of graphene nanoparticles

Ready-to-use graphene-related material-added multi-grade oils: characterization and performance in car engine working conditions

“…As expected, viscosity increases adding of PAMA dispersant and decreases as the temperature increases, following an exponential trend with the temperature reciprocal. 56 The addition of IND25 leads to a slight decrease in viscosity (<5%) with respect to oil : PAMA. Such an effect is typically ascribed to the self-assembly of GRM flakes.…”

“…Such an effect is typically ascribed to the self-assembly of GRM akes. 56 In general, the viscosity of the blend is always higher than the viscosity of the pure oil. In the temperature range between 25 °C and 145 °C, the increase ranges from 35% to 15% in the case of 5W-40 and from about 20% to 10% in the case of 5W-30, as depicted in Fig.…”

Recent advances in the applications of graphene materials for the oil and gas industry

“…Pakharukov et al found that GNP–oil interaction is affected by GNP concentration and temperature. 35 At low concentrations of GNP (500 ppm), the dynamic viscosity of the base fluid decreased by 10–17%, and the greatest decrease in viscosity was observed at 50 °C. The viscosity of oil-based graphene NF (GNF) decreased with increasing nanoparticle concentration, while the viscosity of water-based GNF did not decrease with increasing nanoparticle concentration.…”

“…При увеличении концентрации ацетилена до 20% в смеси с моносиланом свойства получаемых продуктов значительно изменяются. Синтезируемые частицы становятся полностью покрытыми слоями углерода в количе- Частицы кремний-углеродного состава с луковичной структурой показали свою эффективность в виде малых присадок в водных суспензиях для увеличения нефтеотдачи [18,19], а также в качестве анодного материала литий-ионных батарей.…”
