Applications of CNT are many, few of them are:
Additives in polymers, catalysts, electron field emitters for cathode ray lighting elements, flat panel display, gas-discharge tubes in telecom networks, electromagnetic-wave absorption and shielding, energy conversion devices, Lithium-battery anodes, for hydrogen storage, for making nanotube composites (by filling or coating), nanoprobes for STM, AFM, and EFM tips, nanolithography, noelectrodes, drug delivery, sensors, reinforcements in composites, supercapacitor, as additive flame retardant and lot more.
