Graphene is the strongest material ever discovered with a tensile strength 200 times greater than steel. Yet it is extremely lightweight weighing only 0.77 mg per square meter.

The carbon atoms in graphene are densely packed in a hexagonal lattice that reinforces the material’s strength. The atomic bonds between carbon atoms allow graphene to withstand immense force without cracking.

This combination of extreme durability and low weight makes graphene ideal for applications like lightweight composites or protective coatings.

Electrical Conductivity

Graphene is the best electrical conductor we know of at room temperature. It has high electron mobility allowing electrical charges to flow rapidly through the material with virtually no resistance.

In fact, graphene shows ballistic conductivity meaning its electrons can travel long distances without scattering. This property enables electrons to flow at speeds of around 1/300 the speed of light!

With this level of conductivity, graphene has the capability to enable ultrafast electronic processing speeds and data transfers. It outperforms traditional semiconductors like silicon.

Thermal Conductivity for Heat Dissipation

In addition to electrical conductivity, graphene also has extremely high thermal conductivity. It conducts heat better than any other known material.

This property allows graphene to rapidly dissipate heat. Even at high temperatures, graphene remains stable and conductive whereas other materials would fail.

Graphene’s heat dissipation abilities make it promising for thermal management applications, especially in electronics where excess heat must be minimized.

Flexibility Without Losing Conductivity

Remarkably, graphene demonstrates high flexibility while still retaining its electrical properties. It can stretch up to 20% without breaking and is not brittle like other materials.

Graphene’s bonds allow it to bend and deform without experiencing cracks and resistance. This makes graphene ideal for flexible applications like wearable electronics, flexible displays, and more.

Transparent Yet Conductive

Graphene is almost completely transparent transmitting 97.7% of light through its single-layer structure. Yet it remains highly conductive to electricity.

This rare combination enables graphene’s use in transparent conductive coatings, electrodes, and optoelectronics. It can even be layered for adjustable light transmittance and conductivity.

For example, graphene coatings on glass could conduct electricity on touchscreens or interactive windows. The possibilities are endless!
