Process
The market differentiates between carbon powder (which is often falsely referred to as NANO CARBON) and genuine CMS material (carbon micro structure), which in our case is 99.8% pure and consists only of CMSs. In essence, three known methods are currently used to produce CMSs. These methods are arc discharge, laser evaporation and chemical, mostly plasma-assisted gas phase deposition, which require in addition to pure raw materials a very high energy consumption.
In collaboration with St. Andrews University, AGT has succeeded in developing two different new, much simpler and therefore more cost-effective methods of producing a wide variety of CMS grades. It is a chemical-catalytic splitting of gaseous carbon compounds (eg hydrocarbons and CO-compounds) with simultaneous construction of carbon-nanotubes and graphene (process name ACA) in deliberately different forms under controlled atmosphere. Carbon dioxide, methane, natural gas or other gaseous hydrocarbon ¬ compounds can be used as input materials. Written confirmations, material evaluations and material samples are available.
Properties, applications and intelligent material solutions
What makes the CMSs interesting is their unique range of properties and applications: the tubes are very stable. The tensile strength of a multi-wall carbon nanotube was found to be 63 GPa, which is about 50 times that of steel, with significantly lower CMS weight. In addition they can be magnetic or conductive, depending on the production process, in which their characteristics can be adjusted individually and directly.
In all of the key industries of today’s technology society there are applications or even applications in products already on the market, e.g. as an additive to various plastics in the field of electronics, in the automotive industry, in lightweight construction or for the production of sports equipment. In the future, CMSs will help to successfully master the energy transition, for example, through improved batteries, more stable rotor blades of wind turbines or through their use in solar and fuel cells.
Aircraft manufacturers, aerospace, automotive and solar industries, medical & pharmaceutical, electronics & computer manufacturers, military & personal protection equipment or sports equipment manufacturers are potential users.
