Properties and Applications of Carbonnanotubes (CNTs)

Abstract

One of the most important inventions of nanotechnology is carbonnanotubes (CNTs). These have great potential in
different fields, hence being studied by many researchers around the world. Along with their light weight and small
size their good conducting properties and high tensile strength makes them perfect to be used in variety of fields.
CNTs have unique mechanical, electrical and optical properties. Presently they are used as fillers in different materials
like in polymers and ceramics. In future, they may find uses in capacitors, transistors, sensors, nanomedicines etc.
They may have some toxic effects. In the present paper here is brief discussion of preparation, properties, uses and toxic effects of CNT
