1. 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 said layer of aligned nanotubes from the substrate.
