CARBON NANOTUBE FIBERS/FILAMENTS FORMULATED FROM METAL NANOPARTICLE CATALYST AND CARBON SOURCE

摘要

Disclosed is a method of: providing a mixture of a polymer or a resin and a transition metal compound, producing a fiber from the mixture, and heating the fiber under conditions effective to form a carbon nanotube-containing carbonaceous fiber. The polymer or resin is an aromatic polymer or a precursor thereof and the mixture is a neat mixture or is combined with a solvent. Also disclosed are a carbonaceous fiber or carbonaceous nanofiber sheet having at least 15 wt. % carbon nanotubes, a fiber or nanofiber sheet having the a polymer or a resin and the transition metal compound, and a fiber or nanofiber sheet having an aromatic polymer and metal nanoparticles.

1. A carbon nanotube-containing fiber made by a method comprising:
providing a polymer or resin that is an aromatic polymer or a precursor thereof; providing an amount of a transition metal compound; dissolving the polymer or resin and the amount of the transition metal compound in a solvent to produce a solution; producing a fiber from the solution;
wherein the fiber is formed using a spinneret or by electrospinning; and heating the fiber under conditions effective to form the carbon nanotube-containing fiber.
