| 摘要 |
The present invention relates to a preparation method of a carbon nanotube-metal composite, the carbon nanotube-metal composite prepared according to the preparation method, and a magnetic wave shielding material or a conductive polymer comprising the carbon nanotube-metal composite. More particularly, the preparation method of a carbon nanotube-metal composite comprises: a) a mixing step of mixing a composition including carbon nanotube, distilled water as a first solvent, a second solvent, and metal nitrate; b) a drying step of evaporating the distilled water and the second solvent in the composition; c) an oxidation step of converting nitric acid of the metal nitride in the composition into nitrogen oxide, and converting metal into metal oxide; and d) a reduction step of reducing the metal oxide into metal. The preparation method of the present invention can prepare a carbon nanotube-metal composite in a large quantity while generating little amount of industrial wastewater. |
