We have studied the effect of shear flow on the self-assembly of ABC amphiphilic copolymers in dilute selective solutions by changing the stirring rate and the composition of the triblock copolymer. The results revealed that the self-assembled morphology strongly depends on the stirring rate and the composition of the copolymer. The self-assembled morphology formed by the ABC triblock copolymer in selective solvent is the result in a competition between the shear flow and the interfacial tension of the micelles.
