Manufacturing method of precursor fiber for obtaining carbon fiber of high strength and high modulus |
| abstract |
The present invention provides a method for producing precursor fibers that can produce high strength and high modulus carbon fibers. The method of this invention is a process of preparing the aqueous solution of a positive molecule; Adding a carbon nanotube to an aqueous solution of the amphoteric molecule, dispersing the carbon nanotube to prepare a carbon nanotube dispersion; Mixing the carbon nanotube dispersion liquid, the polyacrylonitrile-based polymer, rodan salt or zinc chloride to prepare a spinning stock solution; A step of obtaining coagulated sand from the spinning stock solution by a wet or dry wet spinning method; And stretching this coagulated yarn to obtain a precursor fiber of carbon fiber. |
