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.
