Rope-like bundles of single-walled carbon nanotubes (SWNTs) similar to those obtained by laser vaporization and electric-arc techniques were synthesized on a relatively large scale at low cost the catalytic decomposition hydrocarbons temperature about 1200 °C using an improved floating catalyst method. The SWNTs thus have larger diameters are self-organized into ropes. addition thiophene was found be effective in promoting growth increasing yield either or multiwalled under different conditions.
