<p><P>PROBLEM TO BE SOLVED: To provide a resin composition containing carbon nanotube, in which carbon nanotube is uniformly dispersed in the resin by a simple method, without causing recoagulation in the resin, without impairing characteristics of the carbon nanotube itself, and without performing troublesome operations such as acid treatment, solvent removal etc., to provide its cured substance and its molded body which are excellent in mechanical strength (bending strength and a flexural modulus of elasticity) and in electrical conductivity (in particular uniformity of electrical conductivity), and further to provide a manufacturing method of the resin composition containing carbon nanotube. <P>SOLUTION: The resin composition containing carbon nanotube is formed by adding ultrafine anhydrous silica powder (c), with a particle size of 1-50 nm, of 0.1-3.0 mass% with respect to the total amount of a resin (a) and carbon nanotube (b) and high-shear mixing them, in mixing the carbon nanotube (b) with a diameter of 1-80 nm and an aspect ratio of 50 or more of 0.01-5.0 mass% with the resin (a) and dispersing it therein. The cured substance, the molded body, and the resin composition containing carbon nanotube are obtained. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
