Shear induced orientation of phase segregated block copolymer/epoxy blends

In this work a phase segregated blend system consisting of a block copolymer (BCP) and epoxy matrix with cylindrical morphology is considered. Transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS) investigations reveal that long-ranged ordered nanostructures can be obtained under certain preparation conditions. The pre-shearing conditions are the most important factors in order to obtain regular structures. (C) 2013 Elsevier Ltd. All rights reserved.
