The industrial lubricant also includes at least one intercalation compound of a metal chalcogenide, a carbon containing compound and a boron containing compound, wherein the intercalation compound may have a geometry that is a platelet shaped geometry, a spherical shaped geometry, a multi-layered fullerene-like geometry, a tubular-like geometry or a combination thereof.
GRAPHENE-BASED LUBRICANT ADDITIVES AND LUBRICANTS
A graphene-based lubricant is provided that includes a graphene-based additive. The graphene-based additive, along with and other optional additives is dispersed in a base liquid. A method of lubrication is also provided that includes the application of the composition to two mating surfaces to form a protective coating between the two mating surfaces.
Giant electrorheological fluid surfactant additives
GER fluids are improved by the addition of a polar molecule additive. By addition of a polar molecule additive, yield stresses under electric field are improved by over 50% while the current density is reduced to less than a quarter of the original GER. The reversible response time still remains the same, and the sedimentation stability is greatly enhanced. The zero field viscosity of the modified GER fluid remains the same as that of the original GER fluid without the additive. The improved GER characteristics improve general functionality as an electrical-mechanical interface, attendant with applications to car clutches, fluid brakes, and vehicle shock absorbers.
