Paper reports successful use of nanocomposites to absorb electromagnetic radiation
The rapid development of modern electronic equipment and wireless devices has resulted in severe electromagnetic (EM) radiation pollution, which has implications in the health of creatures from fruit flies and frogs to horses and humans.
In addition, EM radiation can affect the normal functioning of electronics. These issues have prompted researchers to explore ways to create materials that can effectively absorb EM waves.
According to Tsu-Wei Chou, Pierre S. DuPont Chair of Engineering at the University of Delaware, carbon nanotubes (CNTs) offer the unique potential to be excellent EM wave absorbents, with most of the research effort to date focused on CNTs decorated with magnetic metal or metal oxide particles for enhancing magnetic attenuation.
