Abstract

Summary: Self-assembly is an interesting strategy for the creation of periodic structures at the nanoscale. The microphase separation in a linear ternary block copolymer consisting on three immiscible components (ABC), give rise to the formation of different final morphologies that can be controlled by various parameters. In this work, the morphologies of three poly(styrene-b-butadien-b-methyl methacrylate) triblock copolymers with similar molecular weight and their blends with PS homopolymers were studied by atomic force microscopy (AFM). Redistribution of the homopolymer in blends generates new structures could be tailored according to the desired applications.
