Abstract
A method for manufacturing a carbon nanotube-blended aggregate of the present invention includes the steps of: (1) providing an aqueous solution of a water-soluble polymer having a concentration of 0.005 to 3.0% by mass; (2) impregnating carbon nanotubes with the aqueous solution of the water-soluble polymer in a proportion of 400 to 1,000 parts by mass relative to 100 parts by mass of the carbon nanotubes to prepare a wet aggregate; (3) shear-crushing the wet aggregate to obtain an aggregate of crushed products and (4) drying the aggregate of the crushed products to obtain a carbon nanotube-blended aggregate containing the water-soluble polymer.
