Abstract: Methods for reshaping graphene oxide sheet-containing structures using water are provided. Graphene oxide sheet-containing structures can be reshaped by applying a force to a graphene oxide sheet-containing structure, wherein the force changes the initial shape of the structure to a new shape. While the force is still acting on the graphene oxide sheet-containing structure, liquid water is applied to the structure to dissipate stress induced by the force and the structure is then dried. When the force is removed, the graphene oxide sheet-containing structure remains fixed in the new shape.

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.).
