Abstract: A composition is provided. The composition includes carbon nanotubes (CNTs) and a base fluid. The carbon nanotubes are dispersed in the base fluid. The carbon nanotubes are functionalized prior to the dispersion of the carbon nanotubes the base fluid. A method for preparing a composition is provided. The method includes subjecting carbon nanotubes (CNTs) to a ball milling process to reduce the length of the CNTs; oxidation of the ball milled CNTs to functionalize the CNTs, and dispersion of the oxidized ball milled CNTs in a base fluid.

Abstract: A method for preparing a nano suspension lubricant comprises providing substantially spherical nano particles of size ranging from about less than 50 nanometers to about 100 nanometers. The method further comprises mixing the nano particles and a surfactant in about 1:1 ratio in a solvent to form a mixture. The solvent is evaporated from the mixture to obtain surface modified nano particles. The surface modified nano particles include the nano particles coated with the surfactant. The method comprises mixing the surface modified nano particles with a lubricating fluid to form the nano suspension lubricant, where the lubricating fluid comprises about 90% to 99% base oil and about 1% to 10% additives.

Abstract: The present subject matter describes a method for preparation of a lubricant dispersed with carbon nanotubes (CNTs) and a lubricant dispersed with the CNTs prepared thereof. The method comprises ball milling the CNTs and purifying the ball milled CNTs to remove impurities in the CNTs. The method also comprises oxidizing surfaces of the purified CNTs by adding the purified CNTs to a solution comprising at least one oxidizing acid and then refluxing the solution. The oxidized surfaces of the CNTs are modified by adding the CNTs to a solution comprising at least one fatty acid to obtain surface modified CNTs. The method also comprises dispersing the surface modified CNTs in a lubricant to obtain the lubricant dispersed with CNTs.
