Nanotubes Show Their Strengths in Polymer Fbres

Abstract:
Researchers at Queen Mary, University of London and Nanoforce Technology Ltd. in the UK, have successfully produced single-walled nanotube reinforced polymer fibres and tapes that are as strong as theory predicts.

The work shows for the first time the true reinforcing potential of single-walled carbon nanotubes (SWNTs) with effective properties of nanotubes in composites, which are close to their theoretical values.

Prof. Ton Peijs, who heads the research team said: "The problem with carbon nanotubes has always been that despite their amazing potential of becoming the ultimate reinforcing fibre for the next generation of high-performance composites, their success in actually delivering these mechanical properties when embedded in polymer composites has been limited. Despite promises of tensile strengths of 100 GPa or more - 15 to 40 times higher than carbon fibres - their efficiency after embedding them in polymer matrices has often been poor with effective reinforcing properties not far better than those of carbon fibres".
