Controlled reversible debundling of single-walled carbon nanotubes by photo-switchable dendritic surfactants

摘要

Stimulus responsive surfactants based on dendritic glycerol azo-benzene conjugates were used to solubilize and debundle single-walled carbon nanotubes in aqueous media. Their debundling property as well as their reaggregation behavior upon irradiation with light was examined and light triggered reversible bundling and precipitation are shown.
