Goodfellow introduces 3 forms of Multi-Walled Carbon Nanotubes

Engineering Materials Live exhibitor Goodfellow has recently announced the availability of Multi-Walled Carbon Nanotubes (MWCNTs) in three different forms: regular powder, ‘chunky’ powder, and free-standing ‘carpets’. All three forms are produced by means of a catalytic chemical vapour deposition (CCVD) process and can be discussed at the forthcoming Engineering Materials Live event on March 12th.

The company states that ‘Regular’ powder is available in research quantities of several grams up to economical mass production quantities of several kilos. ‘Chunky’ powder (which is exclusive to Goodfellow) is said to be safer, is easily dispersed via sonication into a polymer matrix and is available in small quantities for research.  Free-standing, vertically aligned MWCNTs arrays (called ‘carpets’ or ‘forests’ and also exclusive to Goodfellow) are distinguished by their unique anisotropic properties. Current research revolves around potential uses as free-standing membranes and filters, thermal interface materials, in electronic devices and supercapacitors, and by embedding them in polymer matrices for the production of innovative composites. MWCNTs ‘carpets’ are available in small quantities for research.

Carbon Nanotubes are tube-shaped materials composed of Carbon atoms covalently bonded in hexagonal network, having a nanometric diameter. As an additive in composites, they can improve the mechanical, thermal or electrical properties of a material, offering benefits such as high electrical conductivity, good processability, flame retardancy, thermal dissipation, UV resistance and more. Industries where these attributes are especially beneficial include aerospace, automotive, electronics, energy, oil and gas, coatings, and sporting goods. In addition, there is a great deal of ongoing research into new applications for this remarkable nanomaterial. These new materials, and much more from Goodfellow, can be discussed on the company’s stand at the forthcoming Engineering Materials Live event on March 12th.
