Additional information:

ASSEMBLY STRUCTURE:

The inner diameter of the individual multiwalled carbon nanotubes that are part of the carbon nanostructures ranges from 3-8 nm and the outer diameter ranges from 5 to 20 nm, The number of walls ranges from 2-14. Carbon nanostructures (CNS) are cross linked and branched multiwalled carbon nanotubes in which internal carbon nanotube walls are shared between adjacent tubes and can be considered a highly structurally entangled polymer of multi-walled carbon nanotubes.

RIGIDITY:

CNS structure is not rigid. It can be considered a highly entangled polymer of multi-walled carbon nanotubes. The final particle size of CNS flakes is micron-sized (approximately 20µ to 120µ in three dimensions). TEM images are shown in Section 1.4.
