Graphene, a material made up of single carbon atoms arranged in two layers, has been hailed as a game-changer in materials science and engineering due to its unique properties. Its discovery was based on extensive experiments that revealed the extraordinary ability of graphene to conduct electricity and heat at incredibly high speeds.

In 2004, a team of scientists led by per Edsger D. Skubert discovered graphene through a simple experiment involving placing graphite between a battery and an electron source. The results showed that graphene could act as a conductor for electricity without breaking down into smaller pieces like conventional metals.
The discovery of graphene excited the scientific community, and it soon became clear that this material had enormous potential in various applications such as electronics, energy storage, and biomedical devices. However, there were still many questions surrounding the nature of graphene, such as its stability and resistance to water and oxygen.
In 2011, a group of researchers at the University of Chicago conducted a series of experiments that resolved one of these questions. They found that graphene is highly stable under certain conditions, meaning that it can maintain its properties over long periods of time without breaking down. This was important because it confirmed the existence of graphene and opened up new avenues for its application in the future.
In addition to its remarkable electrical conductivity, graphene also exhibits remarkable thermal conductivity. It can conduct heat much faster than conventional metals, making it an ideal material for use in cooling systems and electronic devices. Graphene is also lightweight and strong, which makes it suitable for use in aerospace and automotive industries.
Despite its impressive properties, graphene faces several challenges in practical applications. One of the main challenges is its high cost, which is due to the complexity of growing and separating the individual carbon atoms in the material. Additionally, graphene’s small size and low density make it difficult to incorporate into traditional materials, which limits its use in practical applications.
Over the past decade, several companies have entered the market to develop graphene-based products. These include companies that specialize in graphene-based electronics, such as graphene.com and Ginkgo Biopharmaceuticals; companies that produce graphene-based textiles, such asSilkogrids; and companies that create graphene-based coatings and adhesives, such asGore-Tex.

Overall, the discovery of graphene has revolutionized materials science and engineering. Its exceptional properties, including high electrical conductivity, thermal conductivity, and stability, have led to the development of new applications in areas such as electronics, energy storage, and biomedical devices. While there are still challenges to overcome, graphene has the potential to change the world we live in and will continue to be a major focus of research and development in the coming years.
