![]() He could even recognize that some of these tubes consisted of only one layer of rolled-up graphite This time they were produced by the gas-phase process (Chemical Vapor Deposition). 1970s – Precisely in 1976 Morinobu Endo observed these tubes again.What was even more interesting was that these layers were separated by the same spacing as the planar sheets of graphite These tubes seemed to consist of graphitic layers of carbon. In fact, he observed straight, hollow tubes of carbon. While doing so he found till that time unknown carbon fibre. 1960s – Roger Bacon at Union Carbide, studied carbon under conditions that were near to its triple point.In 1958 Hillert and Lange made n-heptane decomposition on iron at 1000 ☌ and they also observed a growth of nanoscale tubular carbon filaments In 1955 the trio scientists Hofer, Sterling and McCartney observed a growth of tubular carbon filaments of 10 – 200 nm in diameter. Radushkevich and Lukyanovich published a paper that showed hollow graphitic carbon fibers that were 50 nm in diameter (the Soviet Journal of Physical Chemistry). 1950s – There are three major events that had indicated the discovery of nanotubes.Let’s have a closer look at the series of events that eventually led to the discovery of nanotubes.Ī Brief History of Carbon Nanotubes until Its Discovery That was in the 80s, what you should know is that the nanotubes (also known as buckytubes) had actually been discovered about 30 years earlier, but unfortunately they were not fully appreciated at that time. From that moment the chemical, physical and also material worlds would never be the same. In fact this discovery of buckyballs was an absolute breakthrough. In that time the chemists thought there is nothing more to learn about this element. Thanks to a confluence of events the scientists that were originally investigating something else discovered a molecule that was made purely of carbon. You might have heard about the much unexpected discovery of Buckminsterfullerene in 1985. What Are Nanotubes – Properties that Have Drawn Attention of the Scientists All around the Worldīefore we get to the point, we should start from the very beginning.
