CARBON NANOTUBE COMPOSITE MATERIAL AND CONDUCTIVE MATERIAL |
| 摘要 |
Provide is a carbon nanotube composite material and conductive material to solve the problems of the prior art described above by providing a high conductivity and showing excellent durability against repeated stress such as strain. A carbon nanotube composite material of the invention is a conductive material having carbon nanotubes dispersed in a matrix including observing a peak in each region of 110±10 cm−1, 190±10 cm−1 and 200 cm−1 or more in a Raman spectroscopic analysis at a wavelength of 633 nm, and a ratio R/R0 of an electrical resistance R after a load of repeated stress of 100 times at 10% elongation with respect to an electrical resistance R0 prior to applying a load is 5 or more. In addition, a conductive material of the invention comprises these characteristics of the carbon nanotube composite material. |
