US 9,096,925 B2 · Nanocomposites consisting of carbon nanotube and metal and a process for preparing the same

Abstract

The present invention relates to a method for preparing a nano-composite comprising carbon nanotube and metal, more precisely a method for preparing a carbon nanotube-metal composite comprising the steps of preparing a dispersion solution by dispersing carbon nanotube in a reductive solvent; preparing a mixed solution by adding a stabilizer and a metal precursor; and reducing the metal precursor by heating the mixed solution, and a carbon nanotube-metal composite prepared by the same. The method of the present invention favors the production of a carbon nanotube-metal composite which is characterized by even metal particles from some nm to hundreds nm in size and even dispersion of those particles to be bound to carbon nanotube.
