Abstract: PURPOSE: A carbon nanotube-polymer nanocomposite with improved tensile strength and elongation is provided to have high strength and electric conductivity by using a melt-mixing method. CONSTITUTION: A manufacturing method of a carbon nanotube-polymer nanocomposite comprises as follows: a step of forming the solution mixture of a hydrophilic polymer, carbon nanotube, and solvent; a step of forming a dispersant by applying external energy to the solution mixture; a step of removing the solvent from the dispersant and obtaining carbon nanotube powder coated with the hydrophilic polymer; and a step of melt-mixing the powder with the polymer. The carbon nanotube-polymer nanocomposite comprises 100.0 parts by weight of a polymer matrix, 0.1-5 parts by weight of a polyvinyl alcohol, and 0.1-20 parts by weight of carbon nanotube which is dispersed in the polymer matrix and coated with the polyvinyl alcohol.
