LUBRICATION MATERIAL USING SELF-DISPERSED CRUMPLED GRAPHENE BALLS AS ADDITIVES IN OIL FOR FRICTION AND WEAR REDUCTION |
摘要 |
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.). |

1. A method for forming a lubrication material, the method comprising:
providing a lubricant base fluid; adding crumpled graphene balls as additives in the lubricant base fluid; and sonicating the lubricant base fluid with the additives 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. |
