Practical Processing of Carbon Nanotubes
Purification Commercially available products of
carbon nanotubes (CNTs) may contain significant
amount of impurities which need to be removed in
the first place.
Cutting Purified CNTs ? suspension in acidic
solution ? sonication in a water bath ?
filtration with a pore filter membrane ? (
polishing ? 2nd filtration ?) storage by
suspension in a surfactant.
