The super strong carbon nanotubes having to take a step back to another competitor able to occupy his position. Made with Boron Nitride nanotubes outperformed its peers largely made of carbon.The diamond and boron have always been present in all four tracks in search of the title of the world’s hardest material.
Chen Xiaoming from New York State University, in the United States, took advantage of the fact that as well as carbon, boron can also form mono atomic leaves. Graphene that is properly wrapped give rise to Boron nanotubes. An eye on practical applications. Chen mixed their Boron nanotubes with polymers, in the same way that carbon nanotubes have been used to strengthen synthetic fibers.
The results were even stronger fibers than the reinforced with carbon nanotubes is 35% stronger.
Nanocomposites in research
“The weakest link in these nano composites is the interface between the polymer and the nanotubes” explained professor Changhong Ke. Explaining that if you break the composite nanotubes remain firm as skewers leaving the surface.
Thus, the improvement of the links or the use of polymers more “affected” the Boron Nitride nanotubes can even more improve the resistance of the composite.
The team claims that the result is enough to enable the use of the new composite planes, spaceships, and even in cars and sports equipment-they mix the epoxy and Boron nanotubes with PMMA (Poly methyl methacrylate).
For this, the Boron Nitride nanotubes will have to become more known so that its production could increase in scale and bring down prices. Today one gram of carbon nanotubes cost about $ 10.00, while the grass of Boron Nitride nanotubes has a estimated cost of $1,000
