Single-walled carbon nanotube films and method and apparatus for fabricating thereof

An apparatus for producing single-walled carbon nanotubes comprising:

• a reaction chamber;
• a mixing zone connected to the reaction chamber;
• a first inlet configured to feed a carrier carbon monoxide gas and a catalyst precursor to the mixing zone;
• a second inlet configured to couple to a carbon monoxide gas source, and receive carbon monoxide gas from the carbon monoxide gas source;
• a piping connected to the second inlet, wherein the piping feeds the carbon monoxide gas into the mixing zone;
• a heat source in thermal connection with the piping and configured to heat the carbon monoxide gas fed through the piping and into the mixing zone, wherein the carrier carbon monoxide gas and the catalyst precursor is configured to be mixed with the heated carbon monoxide gas and reacts to form an aerosol containing single-walled carbon nanotubes (SWCNTs);
• a deposition chamber connected to the reaction chamber through a transfer piping;
• and
• a substrate holder configured to hold a substrate in position to expose a surface of the substrate to the aerosol depositing a SWCNT film on the surface of the substrate, wherein the substrate comprises a flexible membrane filter, and wherein the substrate holder comprises:
• a first roller configured to hold a first roll of an unused flexible substrate wherein the first roll is configured to feed the unused flexible substrate in the path of the aerosol comprising SWCNTs;
• and
• a second roll configured to store the flexible membrane substrate which has been deposited with the SWCNT film.
