Abstract: 본발명은바이오접착제를이용하여아라미드섬유체의표면에그래핀쉬트를접착하여전도성아라미드섬유체를제조한다. 본발명의구현일예로서아라미드섬유체의표면에바이오접착제, 그래핀쉬트및 용매를포함하는접착제용액을코팅한다. 본발명은아라미드섬유체에접착된그래핀쉬트의유연성으로인해아라미드섬유체의굽힘으로인한단락이발생되지않아강도등의기계적물성이그대로유지되며, 전기전도도가크게향상된다. 또한, 본발명은바이오접착제의뛰어난양쪽접착성으로인해아라미드섬유체의표면에유연성을갖는그래핀쉬트가견고하게접착되기때문에아라미드섬유체의굽힘으로인한단락을더욱효과적으로방지한다.

Abstract: The present invention relates to a method to manufacture a conductive aramid fiber and the conductive aramid fiber manufactured thereby. The method to manufacture the conductive aramid fiber puts graphite into an emulsion; generates ultrasonic waves in the emulsion to convert the graphite into graphene and manufactures an emulsion composition with the graphene dispersed; and then, coats the surface of the aramid fiber with the emulsion composition containing the dispersed graphene to manufacture the conductive aramid fiber. The coating amount of the emulsion composition is 0.01-10 wt% based on the gross weight of the coated aramid fiber, the content of the graphene in the emulsion composition is 0.01-30 wt%, and the emulsion to form the emulsion composition is advisably an ester compound or an ether compound. The method to manufacture conductive aramid fiber by the present invention simplifies the process and reduces the manufacturing costs by excluding a separate graphene-preparing process because graphite instead of graphene is put into an emulsion and the graphite is converted into graphene. Moreover, the method to manufacture conductive aramid fiber by the present invention improves the conductivity of the aramid fiber even though a small amount of graphene is used, while preventing the decrease in physical properties such as the strength of the conductive aramid fiber because the amount of graphene added is small, thereby minimizing defective fibers. Furthermore, the method to manufacture conductive aramid fiber by the present invention uses an emulsion having excellent interaction with graphene, thereby improving the dispersibility of graphene in the emulsion composition.

Abstract: The present invention, with regard to the manufacture of aramid fiber by: extruding a spinning dope solution made by dissolving aramid polymer in a sulfuric acid solution through a spinneret; coagulating the spinning dope solution extruded through the spinneret; and washing spun aramid fiber and drying the same, provides a manufacturing method of high-strength aramid fiber characterized by injecting 0.01-0.99 wt% of graphite with respect to the weight of the aramid polymer into the sulfuric acid solution before injecting the aramid polymer into the sulfuric acid solution and dissolving the same, followed by generating ultrasonic waves in the sulfuric acid solution to make the graphite into graphene and disperse and include the graphene in the sulfuric acid solution. The present invention has an effect of excluding a separate graphene manufacturing process in comparison with directly injecting graphene into a sulfuric acid solution previously because graphite instead of graphene is injected into a sulfuric acid solution to make graphene from the graphite. In addition, the present invention enhances the liquid crystallinity of a spinning dope solution and remarkably improves the orientation and strength of spun aramid fiber by dispersing graphene excellent in interaction with aramid polymer into a sulfuric acid solution to make the spinning dope solution. The aramid fiber manufactured according to the present invention exhibits a high strength of 28-32 g/d.
