Carding to Align Dry As-Produced Single Wall Carbon Nanotubes

By Lac Nguyen

Mentor: Dr. Kelley Bradley

A single wall carbon nanotube

• A one dimensional cylinder

• Treated a one dimensional (1D) material

• Created of one-atom-thick nano carbon sheets

Nanotube alignment/spinning

• Include of many layers of conductive nanotube networks

• The film resistivity becomes extremely dependent on the measurement, when nanotubes are powerfully aligned

What is carding?

• A mechanical action that divide individual fibers

• Fabricate continuous web

• Card unorganized clumps of fibers into individual fibers to be parallel with each other
