About carbon nanotubes (CNTs)
related to this project
Carbon nanotubes (CNTs) are
nanomaterials made solely of carbon atoms. The highly oriented
multi-walled CNT, for which this project promoted the
development of synthesis process and applications, is a
distinctive nanotube with aligned directions, diameters and
lengths. Potential applications are wide-ranging including
CNT-resin composite materials, electrodes for capacitors, fuel
cells and solar cells, as well as high-performance materials
created by combining various CNT fiber making
technologies.
※The project is now closed as of
October 2017．
Samples are provided by project participating
companies and are all paid.

Applications of vertically aligned
CNTs
Dispersion liquid sample for
Transparent conductive film
Adding
dispersing agents in a water or Organic solvent made
dispersions of long CNTs possible. Dispersion can be kept for
about 3 months.
Only a small amount of CNTs will prove
effective so 1 liter of dispersion liquid with 0.1 wt% CNT
concentration is supplied.

Electrically conductive fluorinated resin
(PTFE) with ultra-low CNT content
|
Volume resistivity as high as 102 Ω-cm 〜103 Ω-cm was achieved
by containing 0.05 wt% of CNTs in fluorinated resin.
Leveraging the permeability of supercritical carbon
dioxide, CNTs are deposited and immobilized on the
super-surface layer of fluroresin particles (about few
µm). This enables high electrical conductivity with a
very small amount of CNTs. |
