Material of the future
High electrical conductivity
Approximately 1.5 times that of silver, the best-conducting metal.
High thermal conductivity
Thermal conductivity ~ 4000 W m⁻¹ K⁻¹, nearly the highest among all known materials.
Exceptional mechanical strength
Tensile strength of 1.3 × 10¹¹ Pa, stronger than steel by about 200 times, similar to the strength of diamond.
Outstanding elasticity and flexibility
Similar to rubber threads, graphene can stretch up to 20% of its original length when under tension.
Ultra-lightweight
A square meter of graphene weighs only 0.77 milligrams. With a mass of less than 1 gram, graphene sheets can cover an entire soccer field.
Transparent
Graphene allows up to 98% of light to pass through.
Applications of nano Graphene
Possessing the above superior properties, graphene offers many potential applications,
including the following outstanding applications:
Electronics: Graphene is utilized in the fabrication of transistors and microcircuits in electronic devices, advancing the generation of high-speed, energy-efficient computers compared to current silicon-based computers.
Optoelectronics: Graphene is employed in the production of optical sensors, optoelectronic transmitters and receivers in optical communication systems, and high-resolution cameras.
Energy storage and conversion: Graphene can be incorporated into lithium batteries, lithium-sulfur batteries, supercapacitors, fuel cell electrodes, and solar cells.
Environmental protection: Graphene is non-toxic and possesses the capability to absorb pollutants up to 600 times its own weight. Furthermore, graphene can be recycled after multiple uses.
Automotive, maritime, and aerospace industries: Due to graphene's durable and lightweight properties, composite materials containing graphene are gradually replacing heavy steel in these industries.
