What is it about?
Through molecular dynamic simulation we tried to understand the role of each block copolymer domain in the dispersion of carbon nanotubes.

Why is it important?
The hydrophobic nature of the lipophilic doamin systematically ensures a higher CNT surface coverage that allows for weaker intertube contacts and makes phase separation more difficult, a higher interstitial water depletion, a much lower degree of water ordering. In none of our simulations have we observed hydrophilic chains extending and swelling in the aqueous domain. Nevertheless, in the present study, the available SWCNT surface was always higher than the potential coverage of the polymer.
