Abstract: A method for producing carbon nanotubes grafted with a vinyl polymer is provided to minimize degradation of physical properties of carbon nanotubes, including a drop in aspect ratio, to allow uniform dispersion of carbon nanotubes in a polymer matrix without aggregation of carbon nanotubes, and to improve the interfacial adhesion between carbon nanotubes and a polymer. The method for producing carbon nanotubes grafted with a vinyl polymer comprises the steps of: (a) oxidizing carbon nanotubes in the presence of a strong acid to obtain carboxyl- or hydroxyl-functionalized carbon nanotubes; (b) performing an urethane reaction between the carboxyl- or hydroxyl-functionalized carbon nanotubes and a diisocyanate compound to introduce isocyanate groups into both terminals of the carbon nanotubes; (c) reacting the carbon nanotubes having isocyanate groups with an acryl amide or hydroxyacrylate monomer having a vinyl group to obtain vinyl-functionalized carbon nanotubes represented by a formula 1; and (d) polymerizing the vinyl-functionalized carbon nanotubes represented by the formula 1 with vinyl monomers to form vinyl polymers grown on the surfaces of the carbon nanotubes. In formula 1, each of M and M' is a monomer containing a vinyl group double bond, with the proviso that M and M' are the same or different.
