ELECTROMAGNETIC-WAVE-ABSORBING MATERIAL, ELECTROMAGNETIC WAVE ABSORBER, AND METHOD FOR MANUFACTURING SAID MATERIAL AND ABSORBER

摘要

This electromagnetic-wave-absorbing material contains surface-treated fiber-form carbon nanostructures, in which the surfaces of the fiber-form carbon nanostructures have been treated, wherein, on the surfaces of the surface-treated fiber-form carbon nanostructures, the amount of elemental oxygen present is 0.030-0.300 times the amount of elemental carbon present, and/or the amount of elemental nitrogen present is 0.005-0.200 times the amount of elemental carbon present.
