Abstract

A self-consistent field theory was applied to confined films of symmetric ABC triblock copolymer melts. The A-B, B-C and A-C interactions were identical and A and C blocks were equal in size. The emphasis in the bulk system was on the regime where B forms the majority domain and the minority A and C domains for cylinders or spheres. The morphologies of confined films were shown to have different symmetries from bulk melts. It was also noticed that the shape and orientation of the minority A and C domains could be manipulated by tuning the wall potentials and film thickness.
