Title:
CONDUCTIVE FIBER COMPRISING METAL NANOBELT AND CARBON NANOMATERIAL COMPOSITE, METHOD FOR PRODUCING CONDUCTIVE FIBER, FIBROUS STRAIN SENSOR, AND METHOD FOR PRODUCING FIBROUS STRAIN SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/209475
Kind Code:
A1
Abstract:
The present invention relates to a conductive fiber comprising a metal nanobelt and carbon nanomaterial composite, a method for producing the conductive fiber, a fibrous strain sensor, and a method for producing the fibrous strain sensor, and the subject matter of the present invention necessitates the inclusion of a step of preparing a composite comprising carbon nanomaterials and metal nanobelts and a step of producing a conductive fiber by mixing the composite with a polymer. Accordingly, the present invention can obtain the conductive fiber and the fibrous strain sensor: which increase the conductivity of the conductive fiber by combining the metal nanobelts making surface contact; in which the adhesion between the carbon nanomaterials and the metal nanobelts is excellent, since the metal nanobelts are combined onto the surfaces of the carbon nanomaterials; and which comprise the metal nanobelt and carbon nanomaterial composite in an evenly dispersed state and having excellent dispersability. Further, the present invention can be applied to the strain sensor according to the principle whereby, when the metal nanobelts making surface contact are subjected to tensile strain, the distance between the metal nanobelts arranged in the direction of the fiber increases, thereby causing a rapid increase in resistance.
