  1. Very thin solar cells capable of converting solar energy into electrical energy with an efficiency up to 60% higher than that of the best solar panels currently on the market.
  2. Extremely light aircraft and that can therefore also be electrified.
  3. Batteries with storage capacity and charging times that are unthinkable today.
  4. Innovative hydrogen storage systems in graphene lattices. They could be used to fabricate mobile electricity generators, that would be powered by hydrogen extracted from air.
  5. Huge breakthroughs in consumer electronics: folding computers, smartphones and tablets, with ultra-thin and resistant displays. Electronic devices could be printed directly on clothes, thus becoming totally wearable. The secret lies in graphene ink: an infinitely thin ink jet will project circuits on any surface.
  6. Extremely fast Internet connection cables.
  7. Very low consumption transistors for portable applications and that would be able to dissipate heat more efficiently.
  8. By covering copper with a thin layer of graphene it is possible to decrease the resistance of the cables used to connect the transistors inside the processors and prevent the performance of the device from collapsing as size decreases.
  9. Its molecular structure allows you to create holes of any size on its surface, thus allowing for very small equipment with zero energy cost to filter and desalinate water. Even bolder applications would be using a sheet of graphene with holes to sequence DNA fragments very quickly.
  10. Applications in the textile world: fabrics with antistatic properties, highly conductive, that shield from electromagnetic waves and are also able to change temperature.
  11. Even edible graphene: the latest discovery about graphene is that it is easily printable on food. American researchers have succeeded in etching edible circuits with a laser, creating a “foam of tiny graphene flakes” on the surface of food, paving the road for ecologically labelled meals.
  12. With graphene contact lenses it will also be possible to see in the dark. Currently used in infrared cameras, they can be used to identify chemicals dispersed in the environment or to monitor blood flow within the human body.
  13. Graphene has also the potential to affect the pharmaceutical industry, enabling the targeted administration of pharmacological components at the cellular level or the creation of bionic implants, such as artificial retinas. Graphene nanoparticles are non-toxic up to a concentration of 50 µg / ml. This means that, at low doses, they are safe for biomedical applications.
  14. Fingerprint sensors that exploit graphene’s high conductivity for lightining fast reaction times. Such a fast sensor could be used to open cars, replacing the classical keys, or to make “smart guns” a reality (fingerprint sensors on the trigger would allow the gun to fire only if held by the owner).
  15. Since graphene is practically waterproof, a graphene-based paint coat could be used to eliminate corrosion and rust. Researchers have even shown that glass or copper plates coated with graphene paint can be used as containers for highly corrosive acids.
  16. Electronics that can integrate with biological systems: It may be possible to implant graphene gadgets that can read the nervous system signals or speak to cells. This could help doctors monitor the human body or could even be used to adjust biological systems for optimal health.
  17. Thanks to the development of a new graphene-based electrode technology, a kind of incandescent “wallpaper” has been developed, which provides a more pleasant and dimmer light than light bulbs, and that is also more energy efficient. In short, illuminated walls similar to those of “Tron” could soon replace light bulbs.
  18. Chemical chimeras are also being developed: compounds of graphene and other materials, such as a speiderweb or a diamond hybrid. A graphene slime can “hear” the footsteps of a spider, while graphene oxide has already been used for holographic displays.
  19. Also 3D spongy constructions were made using graphene sheets, that results in a material 10 times harder than steel and significantly lighter. And it is for this precise combination of strength and lightness that graphene is indicated as a possible material for the realization of science fiction ideas such as space elevators and solar sails. However, we still have to solve the question of the reliability of a 36 km long cable, the minimum length for a space elevator.
  20. It can surprisingly be tuned to behave as an insulator, or even as a superconductor at room temperature. Put simply, the same material can block the flow of electrons or conduct an electrical flow without any resistance. And as if that weren’t enough, graphene nano-tapes can be used as logic gates in quantum computers, and would greatly accelerate their development. The videos below delve deeper into the topic.
