摘要： A conductive fiber including a metal-nanobelt-carbon-nanomaterial composite. A manufacturing method thereof includes preparing a composite including a carbon nanomaterial and metal nanobelts and manufacturing a conductive fiber by mixing the composite with a polymer. A fibrous strain sensor and a manufacturing method thereof are also provided. Thereby, a conductive fiber including a metal-nanobelt-carbon-nanomaterial composite, which is able to increase conductivity of the conductive fiber through synthesis of metal nanobelts enabling area contact and to exhibit good contact between the carbon nanomaterial and the metal nanobelts due to formation of the metal nanobelts on the surface of the carbon nanomaterial and superior dispersion uniformity, and a fibrous strain sensor including the conductive fiber can be obtained. The conductive fiber can be effectively applied to a strain sensor based on a principle by which resistance drastically increases with an increase in a distance between metal nanobelts aligned in a fiber direction upon tensile strain of metal nanobelts enabling area contact.

摘要： A method for manufacturing a conductive film, the method comprising the steps of: preparing a mixture liquid in which a catalytic metal is dispersed in a precursor or a precursor compound of a two-dimensional nanomaterial; and forming a catalytic metal/two-dimensional nanomaterial by irradiating the mixture liquid with ultrasonic waves to generate microbubbles, degrading the precursor compound using energy, which is generated when the microbubbles burst, to synthesize the two-dimensional nanomaterial on an outer wall of the catalytic metal, wherein the method further comprises: dispersing the catalytic metal/two-dimensional nanomaterial in a dispersion to prepare ink; and applying the ink on a substrate and performing rapid air-sintering. Thus, the two-dimensional nanomaterial is synthesized on an outer wall of a non-noble metal having high oxidative characteristics, thereby preventing oxidation of the metal from air and increasing thermal conductivity and electrical conductivity.

摘要： Disclosed are a nanometal-nanocarbon hybrid material and a method of manufacturing the same, the method including modifying the surface of nanocarbon to introduce a functional group to conductive nanocarbon; mixing the surface-modified nanocarbon with an isocyanate-based compound and a pyrimidine-based compound and allowing them to react, thus forming a nanocarbon dispersion reactive to metal ions; adding the nanocarbon dispersion with a metal salt precursor, a reducing agent and a solvent, thus manufacturing nanometal particles; and separating a hybrid of the nanometal particles having the nanocarbon bound thereto. Thereby, nanocarbon is mixed with an isocyanate-based compound and a pyrimidine-based compound and then allowed to react, whereby the nanocarbon reactive with metal ions is used as an additive, thus obtaining a nanometal having a low-dimensional shape having less than three dimensions. Also, a nanometal can be hybridized with nanocarbon simultaneously with the formation of the nanometal, and solvent dispersibility is ensured by a functional group formed by mixing and reacting an isocyanate-based compound and a pyrimidine-based compound, ultimately facilitating the preparation of conductive ink or paste.
