Several purification and processing techniques for laser-produced single wall carbon nanotube (SWCNT) soot were investigated and the resulting changes in the mechanical properties were characterized. SWCNT ribbons had non-nanotube carbonaceous content modified via thermal oxidation and the relationship between oxidation parameters and mechanical strength studied. SWCNT/Polyamide composites were developed and exhibited improved toughness, tensile strength and elongation before break. The composite material is observed to have a greater tensile strength than either the baseline paper or the added nylon.
