Abstract
A carbon nanotube-elastomer composite material according to the present invention is produced by dispersing a carbon nanotube in an elastomer, including a carbon nanotube having a diameter of 20 nm or less, the number of layers of 10 or less, the carbon nanotube being contained in an amount of 0.1 to 20 parts by weight inclusive relative to the total weight of the carbon nanotube and the elastomer, and a continuous network having a Va/Vvalue of 0.5 or more is formed in the elastomer wherein Vrepresents the initial volume of the composite material and Va represents the volume of the structure formed from the remaining carbon nanotubes when the composite material is maintained at a temperature of 400° C. or higher for 6 hours while introducing nitrogen, the elastomer is thermally decomposed and the remaining carbon nanotubes form a structure.
