Method for producing aligned carbon nanotube aggregate

摘要

A production method in accordance with the present invention includes the steps of: providing a catalyst support layer by applying, to a substrate, a catalyst support layer coating agent obtained by 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/or the metal salt; providing a catalyst formation layer by applying, to the catalyst support layer, a catalyst formation layer coating agent obtained by 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/or the metal salt; and growing an aligned carbon nanotube aggregate on the substrate by chemical vapor deposition (CVD).
