Carbon nanotube films possess enormous potential for a variety of applications. The major limitations at present are associated with heterogeneity of as-synthesized nanotubes and with difficulties in separating CNTs with semiconducting and metallic characteristics. If this problem will be solved in...

Fig. 5.30 Absorbance of titania nanotube films as a function of tube length for arrays grown on Ti foil (Type-II) the inner diameter of the tube is 20 nm, wall thickness 10 nm, and barrier layer thickness 100 nm.

The transmittance spectrum of a titania nanotube-film (transparent) on glass is shown in Fig. 5.33. The optical behavior of the Ti02 nanotube-arrays is quite similar to that reported for mesostructured titanium dioxide [133], The difference in the envelope-magnitude encompassing the interference fringe maxima and minima is relatively small compared to that observed in titania films deposited by rf sputtering, e-beam and sol-gel methods [134],... 

The Xi02 nanotube arrays are also well suited for hosting and stabilizing bio-catalysts. Hemoglobin could be immobilized in Xi02 nanotube films and be used as bio-catalyst. It was also observed that adhesion, spreading, growth, and difierentiation of mesenchymal stem cells are critically dependent on the tube diameter. ...

Lamps and displays based on nanotube field emission properties consist essentially of a nanotube film cathode, an extracting electrode, which functions as a gate electrode and a phosphorescent screen, which consists of a transparent conducting anode which is coated with an appropriate phosphor [170,171]. 

Whenever a new material is discovered, the focus quickly shifts from fundamental research to the more applied aspects. Fullerenes and carbon nanotubes are no different in that respect. In the case of fullerenes thousands of new materials are synthesized, but a market-suitable product is not yet available. Perhaps the carbon nanotubes are closer to applications. Graphite fibers have proven to be very useful and nanotubes are at the very least, an extreme in the spectrum of the graphite fiber size scale. They retain many of the favorable properties of graphite and add to them new properties related to their nanoscopic size, as pointed out above. Directions that appear to have some promise involve different properties. Nanotube lamps and displays are already looming on the horizon. Also, nanotube films may be used as electrodes in solid state heterostructures [182].
