Abstract:
1. A method of producing an aligned carbon nanotube aggregate, comprising the steps of: dissolving in an organic solvent (i) an organometallic compound containing aluminum and/or a metal salt containing aluminum and (ii) a stabilizer for inhibiting a condensation polymerization reaction of the organometallic compound and the metal salt to obtain a catalyst support layer coating agent; applying the catalyst support layer coating agent to a substrate; heating the catalyst support layer coating agent to obtain a catalyst support layer on the substrate; dissolving in an organic solvent (a) an organometallic compound containing iron and/or a metal salt containing iron and (b) a stabilizer for inhibiting a condensation polymerization reaction of the organometallic compound and the metal salt to obtain a catalyst formation layer coating agent; applying the catalyst formation layer coating agent to the catalyst support layer; heating the catalyst formation layer coating agent to obtain a catalyst formation layer on the catalyst support layer; and growing an aligned carbon nanotube aggregate on the substrate by chemical vapor deposition (CVD).
