Abstract
The latest advances in the synthesis, properties, characterisation and applications of carbon nanotubes and related materials are presented. The roots of this field and some important historical issues are also reviewed. The mechanical, thermal and electronic properties, as well as applications, of carbon nanotubes are emphasised. These structures have the potential to revolutionise materials nanoscience in the new millennium, because they will be the key components in the fabrication of nanotransistors, robust nanocomposites, conducting polymers, sensors, storage devices, field emission sources and smart materials. However, some important challenges that need to be overcome before real devices are placed in the market are also addressed.
