Abstract
Methods of making improved nanolubricants are providing including dispersing carbon nanoparticles selected from the group consisting of graphene (GN), single-walled carbon nanotubes (SWCNTs), and multi-walled carbon nanotubes (MWCNTs) in a base fluid, such as POE. The carbon nanoparticles are dispersed by adding the carbon nanoparticles to the base fluid to obtain a mixture and mixing the mixture for about 5 minutes using a magnetic stirrer to obtain a suspension. The resulting suspension is then further dispersed using a bath ultrasonicator for about 60 minutes starting at about 25° C. The temperature may be varied up to about 49° C. and back down to about 25° C. over the course of the 60-minute period.
