Abstract

The present invention relates to a fabric material-based flexible electrode and a manufacturing method thereof, and a fabric material-based flexible electrode according to the present invention comprises: a substrate ( 10 ) including multiple fibers ( 11 ) crossing each other; a bonding layer ( 20 ), on the substrate ( 10 ), including an amine group (NH2)-containing monomolecular substance adsorbed thereon; a nanoparticle layer ( 30 ), on the bonding layer ( 20 ), having metallic nanoparticles ( 31 ) coated thereon; and a plating layer ( 40 ), on the nanoparticle layer ( 30 ), having a predetermined metal electroplated thereon.

First claim

The invention claimed is:

1. A fabric-based flexible electrode comprising a substrate made by interlacing a plurality of fibers, a bonding layer formed by adsorbing an amine group (NH 2 )-containing monomolecular material on the substrate, a nanoparticle layer formed by coating metal nanoparticles on the bonding layer, and a plating layer formed by electroplating a metal on the nanoparticle layer,
wherein the monomolecular material is selected from the group consisting of tris(2-aminoethyl)amine (TREN), propane-1,2,3-triamine, tetrakis(aminomethyl)methane, methanetetramine, and mixtures thereof, and
wherein the plating metal is selected from the group consisting of Au, Ag, Ni, Cu, Cr, Ti, and mixtures thereof.

2. The fabric-based flexible electrode according to claim 1 , wherein the fibers are selected from the group consisting of polyester, cellulose, nylon, acrylic fibers, and mixtures thereof.

3. The fabric-based flexible electrode according to claim 1 , wherein the metal nanoparticles are nanoparticles of at least one metal selected from the group consisting of Pt, Au, Ag, Al, and Cu.

4. A method for manufacturing a fabric-based flexible electrode comprising (a) dipping a substrate made by interlacing a plurality of fibers in a dispersion of an amine group (NH 2 )-containing monomolecular material to adsorb the amine group-containing monomolecular material on the substrate, (b) dipping the substrate adsorbed by the amine group-containing monomolecular material in a dispersion of metal nanoparticles to form a nanoparticle layer, and (c) electroplating the substrate, where the nanoparticle layer is formed, with a metal,
wherein the monomolecular material is selected from the group consisting of tris(2-aminoethyl)amine (TREN), propane-1,2,3-triamine, tetrakis(aminomethyl)methane, methanetetramine, and mixtures thereof.

5. The method according to claim 4 , further comprising (d) cleaning the electroplated substrate.

6. The method according to claim 5 , further comprising (e) drying the cleaned substrate.

7. The method according to claim 4 , wherein the fibers are selected from the group consisting of polyester, cellulose, nylon, acrylic fibers, and mixtures thereof.

8. The method according to claim 4 , wherein the metal nanoparticles are nanoparticles of at least one metal selected from the group consisting of Pt, Au, Ag, Al, and Cu.

9. The method according to claim 4 , wherein the electroplating metal is selected from the group consisting of Au, Ag, Ni, Cu, Cr, Ti, and mixtures thereof.

10. The fabric-based flexible electrode according to claim 1 , wherein the nanoparticle layer is a thin film comprising the metal nanoparticles in contact with each other.

11. The method according to claim 4 , wherein the nanoparticle layer is a thin film comprising the metal nanoparticles in contact with each other.
