Note: Carbon nanotubes (CNTs) and graphene are carbon alloys that are unique in terms of electrical, mechanical and other physical properties. Graphene is a two-dimensional material, essentially a single layer of graphite, with carbon atoms housed in a hexagonal grid and a honeycomb.

The carbon nanotubes of hollow cylindrical structures are essentially a graphene sheet that is placed inside a cylinder. The angle at which they roll (their "kayaking") and their diameter affect their properties. Due to the small unit size, nanomaterials have properties that conventional bulk materials cannot match, including superior weight-to-weight ratio (meaning they are strong but light) and superior electrical connection. Carbon-based nanomaterials - Especially graphene and carbon nanotubes - creates huge potential as an alternative to materials in the electronics industry.

The CNT carbon nanotubes  are mixed with graphene current- carrying fillers to provide light-conducting electrical current-  carrying materials with a minimum electrical resistance of  less than 105 m / h. These  graphene nanofibers show a nonlinear  increase  in the amount of electrical conductivity, indicating that this increase is a  function of the amount of phase amplifier. At a certain amount  of nanoparticles, known as the permeability threshold, nanoparticles have the ability to  form a network structure. This causes a sudden increase in the  electrical conductivity of  graphene  nanofibers inside CNTs carbon nanotubes. Inherent conduction and the  ratio of length to width of carbon-based filler nanoparticles make them selective Suitable for achieving this permeability threshold in small quantities of the filling phase  of  graphene  nanofibers inside CNTs nanotubes. The flawless graphene plates  show signs of ballistic transport  . Although the electrical conductivity of graphene, which has been modified  using electrochemical methods, is not as perfect as graphene,  it is still a  viable option  for the production of electroplating graphene nanofibers .

Conclusion: 


Graphene is a substance that is highly effective due to its unusual properties. This material has a  very high electrical and thermal conductivity.
