Carbyne new wonderful material made from Graphene
Carbyne old dream of scientists started at proposed in 1885 by Adolf von Baeyer, who described the existence of linear acetylenic carbon “or an infinitely long carbon chain” known as carbyne.
But, the researcher warned it would remain elusive due to its extreme instability when to make long carbon chain .
Graphene helps scientists to convert old dream to become real researchers from the University of Vienna led by Thomas Pichler have now developed a way to bulk produce carbon chains made up of more than 6,400 carbon atoms.
Previously, the record length for a carbon change was roughly 100 carbon atoms.
How Carbyne made from Graphene:
Now thanks to Graphene can produce Carbyne by a new production method involving rolling up two sheets of graphene to created double-walled nanotubes form a protective tube they then created the Carbyne, the ultra-long carbon chains were then grown inside of these tubes, which create a stable environment, This new tech allowed to form carbon chains more than 50 times longer than the previous record holder by within to stop it from breaking and as a result have managed to synthesise a chain of 6,400 atoms long, which remained stable.
This way to make a long chain by rolling up two sheets of graphene to create Carbyne makes Carbyne is 40 times stiffer than diamond and twice as stiff as graphene, outperforming all other carbon materials in strength.
A material of this kind would be useful in the development of super-strong future devices, the researchers say.
The team’s findings were revealed in science journal Nature Materials and explained how this new method could pave the way for the bulk production of the super material, which is seen as the “holy grail of truly 1D carbon allotropes,” said Lei Shi, part of the physics research team at the university.
“Our results establish a route for the bulk production of exceptionally long and stable chains composed of more than 6,000 carbon atoms, representing an elegant forerunner towards the final goal of carbyne’s bulk production,” it said in the Nature report.
Carbyne features and uses:
‘This work provided an example of a very efficient and fruitful collaboration between experiments and theory in order to unravel and control the electronic and mechanical properties of low-dimensional, carbon-based materials,’ said Angel Rubio.
‘It led to the synthesis and characterization of the longest-ever linear carbon chain. These findings provide the basic testbed for experimental studies concerning electron correlation and quantum dynamical phase transitions in confined geometries that were not possible before.’
To confirm the existence of the chain, the researchers used different types of spectroscopy and X-ray scattering.
The findings revealed it is not only stable in these conditions, but the electrical properties are dependent on the length of the chain.
‘Furthermore, the mechanical and electronic properties of carbyne are exceptional,’ Rubio said, ‘and suggest a wealth of new possibilities for the design of nanoelectronic as well as optomechanical devices.’
Carbyne won’t mean a lot to the average person just yet as this breakthrough is only at its nascent stage and it can’t even be seen by the naked eye, however the material’s incredible strength-to-weight paints a very exciting future for construction and mechanical use as well as having excellent electrical conductivity making it a key component for future generations of gadgets and nanoelectronics devices.
