    • This invention relates to a process for preparing a patterned layer of aligned carbon nanotubes on a substrate including: applying a photoresist layer to at least a portion of a surface of a substrate capable of supporting nanotube growth, masking a region of said photoresist layer to provide a masked portion and an unmasked portion, subjecting said unmasked portion to electromagnetic radiation of a wavelength and intensity sufficient to transform the unmasked portion while leaving the masked portion substantially untransformed, said transformed portion exhibiting solubility characteristics different to said untransformed portion, developing said photoresist layer by contacting with a solvent for a time and under conditions sufficient to dissolve one of said transformed and untransformed portions of the photoresist, leaving the other portion attached to said substrate, synthesising a layer of aligned carbon nanotubes on regions of said substrate to which said remaining photoresist portion is not attached to provide a patterned layer of aligned carbon nanotubes on said substrate.

    • This invention relates to a process for the preparation of a substrate-free aligned nanotube film, comprising: (a) synthesizing a layer of aligned carbon nanotubes on a quartz glass substrate by pyrolysis of a carbon-containing material, in the presence of a suitable catalyst for nanotube formation; and (b) etching the quartz glass substrate at the nanotube/substrate interface to release the layer of aligned nanotubes from the substrate. The invention also provides a process for the preparation of a multilayer carbon nanotube film comprising depositing a substrate-free carbon nanotube film onto another nanotube film. Further, the invention provides a process for the preparation of a “hetero-structured” multilayer carbon nanotube film which includes one or more carbon nanotube layers together with layers of other materials, such as metal, semiconductor and polymer.
