AbstractUsing Monte Carlo simulation, we studied the vesicle formation and microphase behavior of ABC triblock copolymers in selective solvent for A and C blocks. Simulation results show that the hydrophilicity of Blocks A and C determines not only the vesicle formation but also the microphase behavior. If Blocks A and C are of equal length, then Block A (with lower hydrophilicity) is likely to aggregate on the inner surface, whereas Block C (with higher hydrophilicity) tends to move to the outer surface, forming the ABC (from inside to outside) three-layer vesicle. Simulation results reveal that if the hydrophilicity difference between the two blocks is sufficiently low, then the ABC three layers are formed after the membrane closes (i.e., after the formation of vesicle profile). Otherwise, the ABC three layers are formed before the membrane closes. Furthermore, the effect of chain length and incompatibility between the two amphiphilic blocks (i.e., A and C) is studied and discussed in this article. The shorter block A is much more likely to aggregate on the inner surface, and the incompatibility between A and C must be sufficiently strong to ensure that the ABC copolymer forms an ABC (from inside to outside) three-layer vesicle.
