The critical role of asphaltene nanoaggregates in stabilizing functionalized graphene in crude oil derivatives

Graphene derivatives have been seen as an additive to improve the material properties of bitumen, such thermal conductivity, viscoelasticity, and mechanical strength. However, in our previous work, a critical challenge was identified. When graphene are incorporated into it leads detrimental effects. This is due poor phase compatibility with asphaltene aggregates, intrinsic aggregates that give bitumen its characteristic properties. In this we focus on tailoring surface chemistry graphene, thorough non-covalent functionalization, achieve aggregates. addition, work also focuses stabilizing functionalized bitumen. To this, -COOH tethers by Molecular wedging method. Thereafter, same molecules form were used stabilize embedding As result, strategy observed be stable compatible Thus, successful environment-friendly developed utilize potential
