THE POWER OF CARBON NANOTUBES:
APPLICATIONS:
—Detection
of Explosives : Explosives
are chemical-based compounds, which, on being initiated to undergo
self-propagating decay, result in a sudden release of heat and pressure. Due to
the low volatility of explosives, absorptive materials such as polymers have
been employed as explosive vapour sensors, with a variety of transduction schemes. While
monitoring these vapours , they accumulate
over the sensing element of the detectors through either condensation or
trapping of the analyte inside the pores.
Once a certain mass threshold of vapours has been achieved, depending on the type of analyte present, detection
occurs.
—Air
pollution filter:
Future applications of nanotube membranes include
filtering carbon dioxide from power plant emissions
—Buckypaper : a thin sheet made
from nanotubes that are 250 times
stronger than steel and 10 times lighter that could be used as a heat sink for
chipboards, a backlight for Chemical nanowires: Carbon nanotubes additionally can also be used to produce nanowires of other chemicals,
such as gold or zinc oxide. These nanowires in turn can be used to cast nanotubes of other chemicals,
such as gallium nitride. These can have very different properties from CNTs.
Solar cells: GE's carbon nanotube diode has a photovoltaic effect. Nanotubes can replace ITO in
some solar cells to act as a transparent conductive film in solar cells to
allow light to pass to the active layers and generate photocurrent.
