Abstract
Dissipative particle dynamics simulations have been performed to study the coassembly behavior of short carbon nanotubes and diblock copolymers in concentrated solutions by modeling nanotubes as cylindrical nanoparticles (CNPs). With varying the hydrophobic/hydrophilic ratio of the diblock copolymers (AmBn) at fixed concentration and fixed chain length (m + n = 15), the influence of the addition of CNPs on the lyotropic mesophases including micellar, hexagonal, and lamellar phases has been examined in detail, in comparison with the reference systems involving spherical nanoparticles (SNPs). The simulations reveal that the one-dimensional nature of CNPs plays an important role in determining the final coassembly superstructures. It is interesting to find that the addition of CNPs has significantly increased the stability of the hexagonal phase of coassemblies by inducing the phase transformations of the micellar-to-hexagonal in A3B12 solutions and the lamellar-to-hexagonal in A7B8 solutions, whereas the la...
