Graphene is a two-dimensional material made up of carbon atoms arranged in a hexagonal lattice.
It has a wide range of potential applications due to its unique properties.
These properties include high conductivity, flexibility, strength, and thermal conductivity.
The applications of graphene can be broadly categorized into electronics, energy storage, composites, and biosensing/healthcare.
5 Key Areas Explored
1. Electronics
Graphene's high electron mobility and conductivity make it an ideal material for electronic applications.
CVD-grown graphene is particularly suited for these uses.
It has potential roles in conductive inks and advanced computing solutions like photonic FPGAs.
Graphene-based optical modulators may also be crucial in future 6G protocols.
2. Energy Storage
Graphene's high surface area to volume ratio and excellent conductivity make it a promising material for batteries and supercapacitors.
It can store more energy and charge faster than other materials.
This could potentially revolutionize fuel-cell technology.
Graphene can be deposited using the CVD process onto various materials, enhancing their energy storage capabilities.
It has also been integrated with hexagonal boron nitride (hBN) and transition metal dichalcogenides (TMDCs) for use in nanoelectronic and optoelectronic industries.
3. Composites
Graphene powders and nanoparticles, produced mainly through the 'top-down' method, are used as additives in polymer composites, coatings, and thermal management systems.
These additives can replace traditional materials like carbon black or enable new functionalities.
They significantly enhance the properties of the composites.
4. Biosensing/Healthcare
Graphene biosensors are being developed for diagnostic digitization, particularly in point-of-care (PoC) applications.
These sensors leverage graphene's conductivity and sensitivity to detect biological markers.
They have the potential to transform healthcare diagnostics.
5. Challenges and Future Prospects
In summary, graphene's exceptional properties position it as a versatile material with applications across multiple high-impact sectors.
However, challenges remain in mass-producing high-quality graphene at a reasonable cost.
This is crucial for its widespread adoption.
