Abstract

qualities rapidly made them the focus of much research. The exceptional qualities are due to the tubular structure of the nanotubes; the nanotubes may be made of carbon or other materials. Graphene sheets of the order of a nanometer in diameter are envisioned as rolled-up graphene sheets. Aspect ratios (length/diameter) are high due to the microns in length. Besides the numerous pure carbon nanotube uses (gas storage, sensors, electronic devices, and electron transport) there are a lot of uses (microscope tips, electron emission devices, etc.).Electromagnetic shielding, for example, where nanotubes are spread in a polymeric matrix antistatic coatings, corrosion-resistant components with a low density and high strength, and lightweight components source of energy Nanotubes are present in modest numbers in an insulating polymeric it has been discovered that adding a matrix to a composite improves both its mechanical and aesthetic characteristics. Polymer carbon nanotube composites are primarily of interest because they are electrically conductive. When the matrix polymer is electrically conductive it often has improved electrical qualities. This technical note offers a review of recent research on both insulating and conductive materials.
