CHEMICALLY ASSEMBLED SHORT CARBON NANOTUBE ELECTROCHEMICAL ELECTRODES WITH HIGH TRANSPARENCY ONTO CONDUCTING SUBSTRATES AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a short and transparent carbon nano-tube catalyst electrode which is chemically combined to a conductive substrate and a manufacturing method thereof. The manufacturing method includes: a first step of mixing carbon nano-tube powder with an acidic solvent and applying a functional group on the surface of carbon nano-tubes; a second step of forming a carbon nano-tube liquid dispersion using the carbon nano-tube powder to which the functional group is applied and another solvent; a third step of treating the surface of the conductive substrate to form a reactor to the functional group separately from the first and the second step; a fourth step of adding a condensing agent to the carbon nano-tube liquid dispersion, making the carbon nano-tube liquid dispersion react to the conductive substrate from the third step, i.e. making the reactor formed on the surface of the conductive substrate and the functional group formed on the surface of the carbon nano-tubes react to each other, and chemically combining the vertically-arranged carbon nano-tubes on the surface of the conductive substrate; and a fifth step of applying post thermal treatment. The present invention is able to improve electrode reaction efficiency of a carbon nano-tube electrochemical electrode and accordingly can replace a platinum dye-sensitized solar cell.
