Nanotubos de carbono: propriedades e aplicações

Abstract

The study of materials at the nanoscale has been responsible for the technological advance in the various areas of science. Research has grown to find new materials that have better efficiency and performance in future applications aiming to benefit society. In this scenario, one of the nanostructures that has stood out are carbon nanotubes, which have excellent electrical, thermal and mechanical properties. A carbon nanotube is nothing more than a sheet of graphene rolled up in the cylinder form. This system presents a relation between their behavior (metric or semiconductor) and the indices (n, m) that characterize them. Graphene and carbon nanotubes have been shown to be potential in nanoelectronic applications: biochemical sensors, nanometer electrodes [26], medicine, civil construction, etc. This paper presents an introduction about the structural and electronic properties of carbon nanotubes as well as the most promising applications for the development of society.
