CNT dispersion , CNT moldings , CNT composition , CNT aggregate and a process for their preparation

摘要

The problem of the present invention attempts to provide a CNT dispersion liquid, a CNT compact, a CNT composition, a CNT agglomerate and method of producing each, the CNT dispersion liquid being stable at a high concentration with very little damage to the CNTs, maintaining excellent electrical properties, thermal conduction and mechanical properties and a high level of dispersion. A CNT dispersion liquid of the preset invention includes a CNT agglomerate arranged with a mesh body formed from a plurality of CNTs, the CNT agglomerate being dispersed in a dispersion medium is provided wherein a CNT agglomerate is obtained by extracting from the dispersion liquid and drying the CNT agglomerate the obtained CNT agglomerate has a pore size of 0.02 µm or more and 2.0 µm or less being maximized a differential pore volume in a pore size range of 0.002 µm or more and 10.00 µm or less measured using a mercury intrusion porosimeter.
