The invention relates to a method for the production of thermally stabilised melt spun fibres, in which polyacrylonitrile (PAN) fibres or PAN fibre precursors produced by melt spinning are treated in an aqueous alkaline solution which comprises in addition a solvent for PAN. Likewise, the invention relates to fibres which are producible according to this method.

A method for making carbon fiber film includes growing a carbon nanotube array on a surface of a growth substrate. A carbon nanotube film is pulled out from the carbon nanotube array, and pass through a reaction room. A negative voltage is applied to the carbon nanotube film. A carrier gas and a carbon source gas are supplied to the reaction room to form graphite sheets on the carbon nanotube film.
