Neutron scattering study of dispersing CNT with surfactant

Single-wall carbon nanotubes (SWNTs) are dispersed in Triton X-100 surfactant solutions.  Small angle neutron scattering measurements indicate an optimal surfactant concentration for dispersion, which may result from competition between maximization of surfactant adsorption onto SWNT surfaces and a depletion interaction between SWNT bundles mediated by surfactant micelles.
