Carbon Nanotube Chemistry The organic chemistry of carbon nanotubes presents us with a new
set of challenges, not the least of which is the complete insolubility of
these materials. We are actively involved with a set of researchers,
including Professors Selegue and Anthony, as well as Dr. Rodney Andrews
at the Center for Applied Energy Research, who are developing new chemical
processes for making nanotube-based composite materials. Chemical functionalization
of nanotubes is essential for dispersion in a composite, as well as for
covalent bonding with the matrix material itself. We have been investigating both classical cylindrical multiwalled carbon nanotubes (MWNTs) as well as a type of nanotube that is composed of a series of stacked cups. This structure resembles bamboo, and it presents a very different surface to the surrounding medium. Cylindical MWNTs present basal plane graphite to the outside, while bamboo MWNTs present graphene edges. This results in a dramatic shift in reactivity, we are able to exploit these differences to producing some interesting changes in structure. Our research is at the interface of molecular chemistry and materials
chemistry, and we collaborate closely with chemical engineers at the Center
for Applied Energy Research. Through this collaboration we are able to participate
in projects where we tailor nanotubes for use in a variety of composite
matrices.
