Researchers from Shanghai Jiao-Tong University Report Details of New Studies and Findings in the Area of Energy Research (High-strength carbon nanotube fibre-like ribbon with high ductility and high electrical conductivity)

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Fullerenes have been presented. According to news reporting originating in Shanghai, People's Republic of China, by NewsRx journalists, research stated, "Macroscopic fibres made up of carbon nanotubes exhibit properties far below theoretical predictions and even much lower than those for conventional carbon fibres. Here we report improvements of mechanical and electrical properties by more than one order of magnitude by pressurized rolling."

The news reporters obtained a quote from the research from Shanghai Jiao-Tong University, "Our carbon nanotubes self-assemble to a hollow macroscopic cylinder in a tube reactor operated at high temperature and then condense in water or ethanol to form a fibre, which is continually spooled in an open-air environment. This initial fibre is densified by rolling under pressure, leading to a combination of high tensile strength (3.76-5.53 GPa), high tensile ductility (8-13%) and high electrical conductivity ((1.82-2.24) x 10(4) S cm(-1))."

According to the news reporters, the research concluded: "Our study therefore demonstrates strategies for future performance maximization and the very considerable potential of carbon nanotube assemblies for high-end uses."
