Abstract

A ternary system consisting of highly immiscible A and C homopolymers and an AB copolymer, with favorable interactions of B and C, was studied using self-consistent mean-field theory. The copolymer was assumed to be asymmetric, with the volume fraction of the B block ranging from 0.2 to 0.4 and the attraction between B and C repeat units was give definite values. It was observed that the copolymer segregated to the interface between the A and C homopolymers. The copolymer changed the preferred curvature of the interface, as was asymmetric in nature. It was also observed that the curvature of the copolymer continues to decrease till it crosses zero and becomes negative, with significant increase in attraction.
