Method for producing precursor fiber for obtaining carbon fiber having high strength and high elastic modulus |
| abstract |
Disclosed is a method for producing a precursor fiber which enables production of a carbon fiber having high strength and high elastic modulus. The method for producing a precursor fiber comprises: a step of preparing an aqueous solution of amphoteric molecules; a step of preparing a carbon nanotube dispersion solution by adding carbon nanotubes into the aqueous solution of amphoteric molecules and dispersing the carbon nanotubes therein; a step of preparing a spinning raw material solution by mixing the carbon nanotube dispersion solution with a polyacrylonitrile polymer and a rhodan salt orzinc chloride; a step of obtaining a coagulated yarn from the spinning raw material solution by a wet or dry-wet spinning method; and a step of obtaining a precursor fiber for a carbon fiber by drawing the coagulated yarn. |
