Graphene Story
Graphene is a two-dimensional material where carbon atoms are arranged in an infinite honeycomb pattern on a flat plane, offering excellent physical and chemical stability. It's often called the "material of dreams.
"The commercialization of graphene has garnered global attention, as it has been widely covered by various media outlets.
Our company, GreatChallenge, is partnering with GrapheneSquare, the first in the world to have large-scale graphene mass production technology, through an MOU to develop graphene-based products.
With graphene's limitless potential, we are also excited to see what kinds of innovative products will be developed.

Mechanical Strength

Graphene’s tensile strength reaches approximately 130 GPa, making it over 100 times stronger than steel of the same thickness. For reference, the tensile strength of steel is around 0.4 to 1 GPa. This incredible strength is one reason why graphene, despite being extremely thin, can withstand deformation without breaking. While diamonds are known for their hardness, graphene's high elasticity makes it both more flexible and incredibly strong.

Tensile Strength
Tensile strength refers to the maximum force or load a material can withstand without breaking. In other words, it is the maximum strength a material can endure when a pulling force (tensile force) is applied at both ends before it fails.

Electrical Conductivity

Graphene possesses high-speed conductivity, allowing electrons to move much faster compared to traditional conductive materials like copper. While the electrical conductivity of copper is about 5.96 x 10^7 S/m, graphene boasts an impressive conductivity of around 1 x 10^8 S/m, and under certain conditions, it can exhibit even higher conductivity. It has also been found that graphene offers much lower resistance to electron movement than silicon.
This characteristic demonstrates graphene's potential for application in various fields such as electronic components, batteries, and transparent electrodes.

Thermal Conductivity
Graphene has a thermal conductivity of approximately 5000 W/m·K, which is significantly higher than copper's thermal conductivity of about 400 W/m·K. Even diamond, with a thermal conductivity of around 2200 W/m·K, does not match graphene.
This makes graphene an ideal material for electronic devices and cooling systems where heat dissipation is crucial.

Flexibility
Despite having an extremely high elastic modulus (1,000 GPa), graphene is a remarkably flexible material with a fracture strain of 20%. Simply put, it is an ideal material that possesses both strength and flexibility, allowing it to remain intact even when bent or twisted while being extremely thin.
In contrast, materials like steel or silicon are strong but lack flexibility, and while diamond and silicon are both hard and strong, they are brittle and not flexible. Graphene, with its excellent strength and flexibility, holds great potential for use in stretchable electronic components and wearable devices.

Lightweight
Graphene excels in terms of being lightweight. Its density is approximately 0.77g/cm³, making it both incredibly light and exceptionally strong. Not sure how light that is? For comparison, steel has a density of 7.85g/cm³, and even aluminum, which is typically considered lightweight, has a density of about 2.7g/cm³. This means graphene is about 10 times lighter than steel and roughly 4 times lighter than aluminum.
As a result, graphene is regarded as an ideal material for structural applications in industries like aerospace and automotive, where a combination of lightness and strength is crucial.
