  • Patent number: 10138439
    Abstract: A method for forming a lubrication material using self-dispersed crumpled graphene balls as additives in a lubricant base fluid for friction and wear reduction. The lubricant base fluid may be, for example, a polyalphaolefin type-4 (PAO4) oil. After the crumpled graphene balls are added as additives in the lubricant base fluid, the lubricant base fluid with the additives are sonicated for a sonicating time period, so that the crumpled graphene balls are self-dispersed in the lubricant base fluid to improve friction and wear properties of the lubricant base fluid. In some cases, a dispersing agent, such as Triethoxysilane, may be added in the lubricant base fluid to enhance stability of dispersion of the crumpled graphene balls in the lubricant base fluid. The crumpled graphene balls may stay stably dispersed in the lubricant base fluid between a lower temperature (such as ?15° C.) to a higher temperature (such as 90° C.).

  • Patent number: 7649024
    Abstract: The present invention discloses a process for preparing a hydrophobic fluid containing metal oxide nanoparticles dispersed therein such as heat transfer fluids or lubricant fluids, including introducing an alkaline aqueous solution (aqueous phase) and an organic solution of an organic acid metal salt (hydrophobic phase) into a rotating packed bed, the two solutions flowing radially through the rotating packed bed under a great centrifugal force, so that the aqueous phase and the hydrophobic phase contact with each other, reactants in the two phases undergo reactions at the interface of the two phases rapidly, and thus metal oxide nanoparticles are formed. The metal oxide nanoparticles stably dispersed in the hydrophobic phase, which is nanofluid.
