Raymor Nanotech, a sister division of AP&C and part of Raymor Industries group, has recently introduced a new high tech product line consisting of Single-Wall Carbon Nanotubes (C-SWNT). Carbon nanotubes, when used as reinforcement fibres, can greatly enhance the characteristics and properties of metals, ceramics and polymers.
Single-Wall Carbon Nanotube materials when combined with Al, Cu, Mg, Ni, Ti, and Sn have clearly demonstrated improved tensile strength, hardness and elastic modulus properties. Aluminium and C-SWNT composites have shown to have improved tensile strength in the order of 129% compared with pure aluminium.
Recent research has demonstrated that titanium/carbon nanotube composite materials produced by PM can significantly increase tensile stress, hardness and yield stress, as well as increasing hardness properties of the metal by as much as 450% combined with an improved elastic modulus of 65% when compared to pure Titanium.
Nanotech C-SWNT are 100 times stronger than steel for a fifth of the weight, conduct heat just as well as diamonds and can support a very large current density (>109 A/cm2). A material with such outstanding properties is ideally suited to applications that include:
- Reinforcing polymers, metals, metal alloys and ceramics
- Electrical and thermal conductivity products
- Electromagnetic shielding applications
- Catalyst support.
Single-Wall Carbon Nanotubes can also be integrated into sensors in order to detect gas and biological compounds. As membrane foam the product can also provide exceptional filtering properties. Raymor states that C-SWNT can also be used as a field emission device and for battery electrodes as well as promote biocompatibility to human tissue.
There are a number of challenges with regards to developing Metal/Carbon Nanotube composite materials. These include dispersion and preservation of the Nanotube structure. Raymor states that C-SWNT could be the key for the future development of advanced metal properties in countless every day applications, adding that the company is committed to developing the best C-SWNT and within the near future, metal/carbon nanotube composite materials.
Raymor Nanotech’s main production facility is located in Boisbriand, Canada and can now claim to be amongst the largest producers of C-SWNT in the world. Contrary to most processes, the Raymor Nanotech plasma torch based technology is continuous. This innovative process is licensed by the National Research Council of Canada and the University of Sherbrooke.
The product is highly graphitised and is available defect free and without multi-wall carbon nanotubes.
