These electric fluctuations on carbon atoms, which are extremely hard to simulate, modulate the interaction of water molecules on the two sides of the sheet,” Ojaghlou said.

Graphene is one of the most prominent nanomaterials,” Ojaghlou said.
The second phase is the exfoliation of this super-expanded graphite in water, where graphene sheets are separated.

Mahdi Shafiei, Ph.D., also a former doctoral student at VCU and author of the paper, said the team’s findings could be explained as showing how a graphene sheet “behaves like a mirror for water molecules.”The project addressed an important area of study for medicine, industry and science: Understanding how liquids — mainly water —interact with surfaces.
If the droplet resembles a sphere, it is “hydrophobic,” like a droplet on a hot pan.In addition to Ojaghlou, Bratko and Shafiei, the paper was also authored by Mathieu Salanne, Ph.D., a professor at Sorbonne Université, and the late Alenka Luzar, Ph.D., a VCU professor of chemistry who passed away in 2019.The study led by VCU researchers speaks to how liquids interact with surfaces.Dusan Bratko, Ph.D., professor in the Department of Chemistry and an author of the paper, said the findings are an important discovery. A wide variety of graphene sheets options are available to you, such as flexible sheet, composite sheet, and reinforced sheet. “In short, we have taken the graphene conductivity into account, and that provides a much better explanation of the wetting of graphene when there is water on the other side.”“In our work, we explain the image charges on conducting graphene for the first time,” Shafiei said.
Abstract Carbon Nanotubes, CNTs, have been described as rolled‐up graphene layers. “Our work has at least two significant impacts: It sheds light on the behavior of water droplets on graphene supported by water, and we expand the theoretical knowledge about conducting graphene and image charges on them. For this to occur the flake must be of comparable size to the wavelength of the undulations, and may provide a means of separating graphene flakes by size. “Its chemical, electrical and mechanical properties underlie a wide range of applications from cellphones to tennis racquet production, and from electronic devices to car manufacturing.
A simple route to achieve covalently-grafted polyaniline (PANI)/graphene oxide (GO) nanocomposites has been developed. This is important as the former scenario occurs in many practical applications.
