Claim:
1. A method for making a carbon nanotube-metal particle composite, the method comprising: providing carbon nanotubes, polymer monomers, a first solution containing metal ions, and a second solution containing carboxylic acid radical ions; mixing the carbon nanotubes and the polymer monomers in a solvent to form a first mixture, wherein the polymer monomers are adsorbed on a surface of the carbon nanotubes; forming a second mixture by mixing the first mixture, the first solution, and the second solution; wherein the polymer monomers, the first solution, and the second solution react with each other to form a coordination complex mixture containing the metal ions, and the coordination complex mixture is adsorbed on the surface of the carbon nanotubes; and adding a reducing agent into the second mixture to reduce the metal ions of the coordination complex mixture to metal particles and simultaneously polymerize the polymer monomers to form a polymer layer on the surface of the carbon nanotubes so that at least part of the metal particles are adsorbed between the carbon nanotubes and the polymer layer.
