Method for making carbon nanotube based composite

摘要

A method for making a carbon nanotube based composite is provided. In the method, carriers, solution containing metal ions, and a carboxylic acid solution are mixed to form a mixed solution containing a complex compound. A reducing agent is added into the mixed solution. The metal ions are reduced to metal particles absorbed on the surface of the carriers. The carriers having the metal particles absorbed thereon are purified to obtain the carbon nanotube based composite.

1. A method for making a carbon nanotube based composite, the method comprising:
providing a plurality of carriers, each carrier comprises a carbon nanotube and a polymer layer coated on a surface of the carbon nanotube; mixing the plurality of carriers, a solution containing metal ions, and a first amount of carboxylic acid solution to form a mixed solution containing a complex compound; adjusting a pH value of the mixed solution so that the pH value is in a range from about 2 to about 8; adding a reducing agent to the mixed solution to reduce the metal ions to metal particles absorbed on the surface of the plurality of carriers, and purifying the mixed solution with the reducing agent added to obtain the plurality of carriers having the metal particles absorbed thereon.
