Abstract

The invention discloses application of a carbon tube film in anisotropic polymer preparing. A modified carbon tube film is coated with polyimide acid in a spinning mode to perform carbon tube film composition, and annealing is conducted in a range of 50-400 DEG C. The application of the carbon tube film in the anisotropic polymer preparing is simple in method, short in period, fast and efficient, easy to operate and low in cost. Oriented carbon tube films are added, and thus mechanical properties of a composite film material are drastically improved, and the composite film material has obvious anisotropy in the horizontal and vertical directions in a plane.
