In a first, researchers in Austria have synthesized Carbyne, a material 40 times stronger than diamond and twice as strong as the strongest known material ‘graphene’.
In the new method, the researchers have used a double-walled carbon nanotube to grow stable carbon chains of record-breaking lengths.
Carbyne, an electrically neutral carbon atom with three non-bonded electrons, has high reactivity that leads to its immediate destruction.
To make it stable, scientists used double-walled nanotubes by rolling two layers of graphene.
Carbyne was first proposed in 1885 by Adolf von Baeyer, who described the existence of linear acetylenic carbon – or an infinitely long carbon chain – known as carbyne.
