Impact of carbon nanotubes (CNTs) on electrical properties of polymers
7 February 2008Scientists at National Institute of Standards and Technology (NIST) have carried out a study on carbon nanotubes/polypropylene composits and found that the electrical properties of the composite can be changed dramatically.
Scientists have found that carbon nanotubes (CNTs) can act as an additive for polymers and a relatively low concentration of it can change the electrical conductivity of the polymer. The technique will be useful in many applications including antennas, aircraft components, electrical packaging, sensors, anti-static hoses and automotive paints.
Researchers at NIST found that electrical properties of conductor depend on composite flow and once the flow is removed, the nanoscale material revers back to its original conductivity. The researchers has proposed a mathematical model for predicting the electrical conductivity behavior of the composite under theoritical conditions.
