Various embodiments of the present invention provide improved carbon fibers and films and methods for making carbon fibers and films. The carbon fibers and films disclosed herein are generally formed from acrylonitrile-containing polymers. Carbon fibers and / or films can also be formed from composites comprising carbon nanotubes, graphite sheets, or both and an acrylonitrile-containing polymer. The fibers and films described herein can be tailored to exhibit one or more of high strength, high modulus, high conductivity, high thermal conductivity, or optical transparency, depending on the intended use of the fiber or film. . |
