What are carbon nanotubes state any 4 applications of carbon nanotubes?
CNTs are examples of true nanotechnology: they are only about a nanometer in diameter, but are molecules that can be manipulated physically and chemically in very useful ways. They find an incredible range of applications in electronics, materials science, energy management, chemical processing, and many other fields.
How is carbon used in electronics?
Carbon, in various forms and in combination of other materials, is widely used in electrical engineering. Electrical carbon materials are manufactured from graphite and other forms of carbon. For making brushes for electrical machines such as DC machines, alternators. For makings parts for telecommunication equipment.
Why graphite is used in electronic?
Graphite’s unique ability to conduct electricity while dissipating or transferring heat away from critical components makes it a great material for electronics applications including semiconductors, electric motors, and even the production of modern day batteries.
How can graphene be used in electronics?
Graphene can be used as a coating to improve current touch screens for phones and tablets. It can also be used to make the circuitry for our computers, making them incredibly fast. These are just two examples of how graphene can enhance today’s devices. Graphene can also spark the next-generation of electronics.
What is the difference between graphene and carbon nanotubes?
Graphene is a two-dimensional material, basically a single layer of graphite, with carbon atoms arranged in a hexagonal, honeycomb lattice. Carbon nanotubes are hollow, cylindrical structures, essentially a sheet of graphene rolled into a cylinder.
What is graphene and its applications?
Since graphene is the world’s thinnest material, it also extremely high surface-area to volume ratio. This makes graphene a very promising material for use in batteries and supercapacitors. Graphene may enable batteries and supercapacitors (and even fuel-cells) that can store more energy – and charge faster, too.
Where are the graphene carbon nanotubes used?
Applications. CNTs and graphene are of interest for many different applications. Being light and strong, CNTs, or composite materials containing CNTs, have been suggested for many uses that require these properties, from clothing and tennis racquets to tissue engineering, bulletproof gear and space elevators.
