The Important Role Of Graphene In Aerospace

wallpapers News 2020-12-24
Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp² hybrid orbitals.
Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered a revolutionary material in the future.
New energy battery
New energy batteries are also an important area of graphene's earliest commercial use. The Massachusetts Institute of Technology in the United States has successfully developed flexible photovoltaic panels with graphene nano-coatings on the surface, which can greatly reduce the cost of manufacturing transparent and deformable solar cells. Such batteries may be used in night vision goggles, cameras and other small digital Application in equipment. In addition, the successful development of graphene super batteries has also solved the problems of insufficient capacity and long charging time of new energy vehicle batteries, which has greatly accelerated the development of the new energy battery industry. This series of research results paved the way for the application of graphene in the new energy battery industry.

Graphene filters are used more than other desalination technologies. After the graphene oxide film in the water environment is in close contact with water, a channel with a width of about 0.9 nanometers can be formed, and ions or molecules smaller than this size can pass through quickly. The size of the capillary channels in the graphene film is further compressed by mechanical means, the pore size is controlled, and the salt in the seawater can be filtered efficiently.
Hydrogen storage materials
Graphene has the advantages of light weight, high chemical stability and high specific surface area, making it the best candidate for hydrogen storage materials.
Due to the characteristics of high conductivity, high strength, ultra-light and thin, the application advantages of graphene in the aerospace and military industry are also extremely prominent. In 2014, NASA developed a graphene sensor used in the aerospace field, which can detect trace elements in the atmosphere at high altitudes and structural defects on spacecraft. Graphene will also play a more important role in potential applications such as ultralight aircraft materials.
