Abstract
A carbon nanotube-elastomer composite material according to the present invention contains carbon nanotubes and an elastomer, which contains the carbon nanotubes in a range of 0.1 part by weight to 20 parts by weight relative to the total weight of the carbon nanotubes and the elastomer, and in which the elastomer has a thermal decomposition temperature of 150° C. or more, and supposing that the resulting storage modulus is E′(t) when the carbon nanotube-elastomer composite material is maintained at 150° C. for t hours, a ratio E′ (24)/E′(0) between a storage modulus E′ (0) at the time of t=0 hour and a storage modulus E′(24) at the time of t=24 hours is set in a range from 0.5 or more to 1.5 or less in the resulting carbon nanotube-elastomer composite material.
