Graphene is a single layer of carbon atoms arranged in a hexagonal lattice structure that has many potential applications, including as a conductive material for electronics and as a material for energy storage. In 2018, a team of researchers from the University of Toronto and the University of California, Berkeley reported the discovery of a new type of graphene that they called “superhydrophobic” (or super water-resistant). This unexpected discovery was significant because it demonstrated that hydrophobic materials could be used in practical applications.

To make superhydrophobic graphene, the researchers used a technique called chemical vapor deposition (CVD), which involves heating a substrate in a vacuum chamber to create a layer of graphene on top of it. However, this process can be challenging because it requires precise control over the temperature and pressure of the substrate and gas mixture. To overcome these challenges, the researchers developed an advanced catalyst that was able to lower the temperatures necessary for CVD without compromising its performance.
The resulting graphene was then characterized using a variety of techniques, including X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the graphene had unique properties, such as a high surface area and a low density of impurities. These features made it possible for the graphene to resist water and other liquids more effectively than traditional hydrophobic materials.
This discovery opened up new possibilities for the use of superhydrophobic graphene in various fields, including aerospace, automotive, and medicine. For example, the researchers suggested that superhydrophobic graphene could be used as a coatings for airplane wings to reduce drag and improve fuel efficiency. They also pointed out that it could be used as a lubricant for engines or as a drug delivery system for medical implants.

Overall, the discovery of superhydrophobic graphene was a significant breakthrough in the field of materials science and has the potential to revolutionize many industries. By developing and scaling up this new type of graphene, researchers hope to create more efficient, durable, and sustainable materials for use in a wide range of applications.
