Elastic conductive fiber manufacturing method

Abstract

The invention belongs to the field of electrode manufacturing technologies and particularly relates to an elastic conductive fiber manufacturing method. The elastic conductive fiber manufacturing method comprises utilizing two motors and a translation stage, fixing two ends of an elastic fiber onto the two motors, and fixing a spinnable carbon nanotube array on the translation stage; pulling out a carbon nanotube thin film from the array and putting the carbon nanotube thin film on the elastic fiber at a preset angle; starting the two motors synchronously to enable the elastic fiber with two ends fixed onto the two motors to rotate along the two motors, continuously winding the continuous carbon nanotube thin film onto the elastic fiber at a preset angle, namely, a helical angle, and enabling the helical angle of the elastic fiber to remain unchanged by setting the movement speed of the translation stage; continuously performing the above process to manufacture and obtain an elastic conductive fiber. The resistance of the elastic conductive fiber can basically remain unchanged under the condition that the stretch rate is 100%. The elastic conductive fiber provides novel materials for manufacturing elastic leaner electronic devices.

technical field [0001] The invention belongs to the technical field of electrode preparation, and in particular relates to a preparation method of elastic conductive fibers. Background technique [0002] With the development of science and technology, the development trend of electronic devices is miniaturization and flexibility. In recent years, small fiber-shaped electronic devices have received extensive attention from the scientific and industrial circles and have been developed rapidly. Many fiber-shaped electronic devices have been fabricated, including supercapacitors [1-4] ,Lithium Ion Battery [5] ,Solar battery [6] , Organic Light Emitting Diodes [7-8] , Field Effect Transistor [9] ,sensor [10] wait. However, these fibrous electronic devices are mainly fabricated based on metal fibers, carbon fibers or carbon nanotube fibers.

AI Technical Summary

Problems solved by technology

Although metal fibers have good conductivity and ductility, they cannot return to their original state after being stretched; while carbon fibers or carbon nanotube fibers have good conductivity, but their fracture lengths are all less than 5%

However, as a woven fiber-like device, a very important characteristic is elasticity, but so far there is no elastic conductive fiber, which affects the development of elastic fiber-like electronic devices
