The goal of this article is to provide an updated and in-depth review of so
me of the most exciting and important developments in the processing and pr
operties of carbon nanotubes. Nanotubes can be formed in various structures
using several different processing methods. The synthesis methods used to
produce specific kinds of nanotubes are discussed and a comparison is made
between the methods used by researchers and industrial producers. This is f
ollowed by an overview and discussion of what makes carbon nanotubes intere
sting to so many: their mechanical, chemical, electrical, thermal, and opti
cal properties. The article ends with a discussion of the future outlook fo
r the study of carbon nanotubes.
