Abstract
A device and method for preparing an aligned carbon nanotube (CNT) fiber through electrochemical stretching. The method comprises: constructing an electrochemical reaction system by using an original CNT fiber as a working electrode stretching, a counter electrode, a reference electrode, and an electrolyte, applying a selected stretch stress to the original CNT fiber for electrochemical stretching while powering on the electrochemical reaction system so that ions in the electrolyte are embedded into the original CNT fiber, and the orientation of the carbon nanotube is generated due to the action of the stretch stress under the state of expansion; and powering off the electrochemical reaction system while maintaining the application of the selected stretch stress, so that the ions in the electrolyte are released, thereby obtaining a highly aligned CNT fiber.
