FIBER TYPE STRAIN SENSOR WITH METAL NANOBELT/NANOCARBON MATERIAL HYBRID MATERIALS, AND FABRICATION METHOD

摘要

The present invention relates to a fiber type strain sensor with metal nanobelt/nanocarbon material hybrid materials, and a fabrication method. The present invention includes a step in which the surface of a nanocarbon material is modified so that a functional group is introduced into a conductive nanocarbon material; a step in which a nanocarbon material dispersion reactive with a metal ion is formed by mixing and reaction between isocyanate and pyrimidine compounds and the surface-modified nanocarbon material; a step in which a metal nanobelt is formed on the nanocarbon material surface by metal salt precursor and solvent addition to the nanocarbon material dispersion and addition speed-adjusted reducing agent addition; a step in which a conductive fiber is fabricated by mixing between a polymer and a nanocarbon material-metal nanobelt hybrid material; and a step in which a fiber type strain sensor is realized by means of the conductive fiber. According to the present invention, the conductivity of the conductive fiber is increased by means of synthesis of the metal nanobelt performing surface contact, and the nanocarbon material-metal nanobelt contactability is excellent because the metal nanobelt is synthesized with the surface of the nanocarbon material. Accordingly, a fiber type strain sensor with metal nanobelt/nanocarbon material hybrid materials that is highly dispersible and evenly dispersed can be obtained. In the case of tensile strain of the metal nanobelt performing surface contact, the distance between the metal nanobelts aligned in the fiber direction increases and resistance rapidly increases, and thus an effect applicable to the strain sensor can be obtained.;COPYRIGHT KIPO 2018
