Enhancing Cuo nanolubricant performance using dispersing agents

This paper reports on the use of organic dispersing agents to prevent the agglomeration of tiny CuO nanoparticles in synthetic oil, by developing low concentrations of nanolubricants with good stability. Tiny nanoparticles were added to polyalphaolefin (PAO) oil with the aid of three organic dispers...
