This allows the addition of different molecular complexes and that can be bonded to the outer cells, effectively changing the properties of the membrane. The CNT synthesis process essentially changes the properties of the carbon network, drastically opening a realm of new opportunities.įor example, in the context of manufacturing free-standing CNT membranes, one can break the outer cells while keeping the inner tubes intact. When synthesized using Canatu’s Floating Catalyst Chemical Vapor Deposition (FC-CVD) method, carbon nanotubes can be customized to have a different number of side walls or a desired mix of them. Modifying carbon nanotubes and their properties In practice, multi walled carbon nanotubes are used in applications that require high mechanical strength. They are longer in diameter, have a higher aspect ratio and are remarkably stronger than the already strong single walled carbon nanotubes. Multi walled carbon nanotubes are cylindrical with concentric, multiple layers of graphene. They are suitable for harsh chemical environments, automotive and other applications that require high mechanical stress such as filtration membranes. On the other hand, multi walled carbon nanotubes are remarkably stronger than the already impressively strong single walled carbon nanotubes. Single walled carbon nanotubes can also benefit electrochemical sensors due to their large surface area that enables extremely high sensitivity. For instance, in practice only single walled carbon nanotubes can be utilized as semiconductors such as transistors. producing single walled carbon nanotubes (SWCNTs), double walled carbon nanotubes (DWCNTs), or multiple walled carbon nanotubes (MWCNTs).ĭifferent applications require different wall types due to their varied properties. One key alteration that can be made is to dictate the number of walls each nanotube has, e.g. Canatu achieves this elevated level of customization through various synthesis processes. Over the years, Canatu has developed its expertise in adapting and modifying aspects of our superior carbon nanotubes to suit different contexts and applications. multi walled carbon nanotubesĬarbon is the most versatile material in the universe.
