Graphene for Commercial Use
February 22, 2023Discovery
Graphene is a two-dimensional material composed of a single layer of carbon atoms arranged in a hexagonal lattice. The discovery of graphene is credited to Andre Geim and Konstantin Novoselov, two physicists at the University of Manchester in the UK. They were awarded the Nobel Prize in Physics in 2010 for their discovery.

Geim and Novoselov first isolated graphene in 2004 by using a simple method known as the “scotch tape” method. They took a piece of graphite, which is a layered material consisting of many stacked layers of graphene, and used adhesive tape to peel off a single layer. They repeated the process multiple times to obtain a small piece of graphene.
To confirm that they had isolated graphene, Geim and Novoselov used various characterization techniques, including electron microscopy and Raman spectroscopy. They found that graphene was an extremely strong material, with a tensile strength of over 130 gigapascals, and had excellent electrical and thermal conductivity properties.
Geim and Novoselov’s discovery of graphene has had a significant impact on various fields, including materials science, electronics, and energy. Graphene is considered a “wonder material” due to its exceptional properties, such as high strength, flexibility, and conductivity, and is being investigated for numerous applications, including transparent electrodes, energy storage devices, and sensors.
Graphene is still in the early stages of commercialization, but some of the most popular products include:
• Graphene-based batteries and supercapacitors
• Graphene-enhanced composites and plastics
• Graphene-based conductive inks and coatings
• Graphene-based sensors
• Graphene-based thermal management materials
• Graphene-based electronic devices and displays
• Graphene-based energy generation and storage products.
It’s important to note that not all graphene products are equally effective, and some claims made by manufacturers may not be supported by independent scientific studies.
Graphene has numerous potential applications due to its unique combination of properties, including high strength, flexibility, and conductivity. Some of the most promising applications of graphene are:
Electronics: Graphene’s high electrical conductivity and high mobility of charge carriers make it an attractive material for use in electronic devices, such as transistors, sensors, and displays.
Energy storage: Graphene’s high surface area and excellent electrical conductivity make it an ideal material for use in energy storage devices, such as batteries, supercapacitors, and fuel cells.
Water filtration: Graphene’s excellent mechanical strength and permeability make it an ideal material for use in water filtration membranes, as it can filter out even the smallest contaminants.
Composites: Graphene can be added to polymers, metals, and ceramics to create composites with enhanced mechanical and electrical properties.
Biomedical applications: Graphene’s biocompatibility, electrical conductivity, and high surface area make it a promising material for use in biomedical applications, such as drug delivery and tissue engineering.
Coatings: Graphene’s high strength and impermeability make it an ideal material for use in coatings, such as corrosion-resistant coatings, anti-fouling coatings, and UV-blocking coatings.
Overall, graphene has the potential to revolutionize numerous industries and could have a significant impact on various aspects of our lives, from electronics to healthcare. However, more research is needed to fully understand graphene’s properties and to develop scalable and cost-effective production methods.
