STRUCTURE CONTAINING CARBON NANOTUBE, METHOD FOR OBSERVATION OF THE SAME AND COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a structure containing carbon nanotubes and sufficiently exhibiting conductivity imparting effect of carbon nanotube and to provide a composite material produced by using the structure.

SOLUTION: The structure containing carbon nanotubes comprises (a) carbon nanotubes and (b) a resin, and satisfies the requirements that the average of the carbon nanotube areal ratio [A1] defined by formula (I) is≥10% and the average of the areal ratio [A2] of the fine aggregate of carbon nanotubes defined by formula (II) is≥25%. Formula (I): areal ratio of carbon nanotube [A1]=[(total occupied carbon nanotube area in the observation area)/(total observation area)]×100 (%), formula (II): areal ratio of fine aggregate of carbon nanotube [A2]=[(sum of the area of fine aggregate of carbon nanotube having a length of≥30μm)/(total occupied carbon nanotube area in the observation area)]×100 (%).
