Abstract:
The interaction with surfactants changes from one carbon nanotube species to
the other. We used this to replace non-ionic surfactants by ionic ones. By
fine-tuning the replacement conditions, we covered some specific nanotubes
with non-ionic surfactants and the others with ionic ones. Addition of salt
triggers precipitation of the species suspended by the ionic surfactant; this
effectively leads to chiral selective enrichment of a carbon nanotube
suspension. We hence produce an (8,4)-enriched suspension by replacing a
polyglycerol-based custom amphiphile with the commercial SDBS and salting with
NaCl.
