Graphene has recently been widely used in lubricants and lubricating additives at multiple scales and allows to reduce considerably friction and to drop wear by 4-5 orders of magnitude.
Several remarkable properties of GUP® make it an effective additive for lubricants. These include low shear strength, high yield strength, chemical compatibility for dispersion in polar and nonpolar lubricants, and high thermal conductivity and an eco-friendly composition.
There are many kinds of additives that can improve the lubricating performances of lubricants, which usually function as friction modifiers, anti-wear additives, extreme pressure agents, anticorrosion agents, antioxidants, and so on. Among these, graphene improves tribological performance, providing excellent friction reduction and anti-wear performances, which are hardly found in other additives.
