Interactions between Block and Comb Copolymers and Single-Walled Carbon Nanotubes in Aqueous Media
Carbon nanotubes are of great interest due to their unique properties, such as their high aspect ratio and electrical conductivity. Many possible applications of CNTs require nanotubes to be well dispersed in suspension. One method commonly reported to disperse nanotubes is sonication with the addition of an adsorbing surfactant or polymer. We plan to investigate the adsorption of sodium dodecyl sulfate, Pluronic ABA block polymers and comb copolymers with grafted poly(ethylene oxide) side chains, which are all effective as dispersants for CNTs. By using contrast matching techniques, we hope to obtain detailed information about the adsorbed polymer layer and exactly how they act on CNTs to stabilise them in water.
