Interactions between block copolymers and single-walled carbon nanotubes in aqueous solutions: A small-angle neutron scattering study

摘要

Polymers have been found to be good dispersants for single-walled carbon nanotubes (SWCNTs), and their interaction with the nanotube surface has been considered using different approaches. One is termed polymer wrapping, which describes a tight compact interaction, whereby the polymer tends to coat the nanotubes in close contact. A second approach suggests loose adsorption, a weaker interaction between the polymer and the nanotube, so that adsorbed polymers still assume a coiled conformation.
