Graphene lubrication additive

Thread Content

Graphene has become a highly focused and prominent area of research due to its unique crystal structure, a wide range of novel properties, and broad application prospects. Graphene’s excellent thermal conductivity, anti-friction and wear-resistant properties, as well as its chemical inertness, make it highly suitable as an efficient and green lubricant additive that confers superior tribological properties on lubricants. Therefore, graphene has become a potential high-performance nanolubricant material. However, the difficulty in stably dispersing graphene in lubricants limits its applications. Therefore, graphene must be functionally modified, and researchers have carried out active and effective work in this area. However, research on the functional modification of graphene is still not well-developed; there is a lack of a systematic understanding of various modification methods and their effects. How can graphene be subjected to predictable and controllable functional modification based on actual needs, and what is the relationship between such functional modifications and its tribological properties? Which organic reagents should be used to modify layered graphene materials in order to maximize the dispersion of the modified graphene in lubricants, while preventing it from agglomerating over an extended period of use? Please have relevant research experts discuss it.
