One of the fastest growing areas of nanotube research is the study of polymer-nanotube composite materials. These materials utilize the excellent strength of carbon nanotubes that has been evident but difficult to harness in the past and show impressive increases in strength relative to the polymer. It is suspected that many of the physical properties observed in these composites are related to the...
A range of multi-wall carbon nanotubes and carbon nanofibres were mixed with a polyamide-12 matrix using a twin-screw microextruder, and the resulting blends spun to produce a series of reinforced polymer fibres. The aim was to compare the dispersion and resulting mechanical properties achieved for nanotubes produced by the electric arc and a variety of chemical vapour deposition techniques. A high...
The effect of varying current density and pressure during arc generation on the yield and purity of multi-walled nanotube-containing carbon soot has been studied in this work. Various soots were produced and characterised qualitatively using transmission electron microscopy and quantitatively using electron paramagnetic resonance and thermogravimetric analysis. It was found that both yield and purity...
