Abstract
The metal non-woven fabric electrode having a surface-polymerized dopamine-based monomer and the surface modification method for the same according to the present invention have the effects that coating an aqueous slurry as well as a dopamine-based polymer layer even on a surface of the metal fiber inside the electrode.
Claims13
A metal non-woven fabric electrode, characterized in that it is formed by a three-dimensional network structure, and
- comprising:
- at least more than one metal fiber which are surface-treated with a hydrophilic organic solvent;
- an air gap formed between the metal fiber;
- and
- a dopamine-based polymer layer coated on a surface of the metal fiber in contact with the air gap.
A surface modification method of a metal non-woven fabric electrode comprising:
- (a) surface-treating a metal non-woven fabric for electrode with a hydrophilic organic solvent;
- and
- (b) surface-polymerizing the dopamine-based monomer to the metal non-woven fabric for electrode surface-treated with the organic solvent.
