Title: A shear stabilized biaxial texture in a lamellar block copolymer

Abstract

Block copolymers spontaneously self-assemble into a variety of morphologies. Recent studies have produced a biaxial texture in poly(styrene-b-ethylene propylene), SEP, diblock copolymers by applying oscillatory shear. This biaxial texture consists of {open_quotes}parallel{close_quotes} lamellae (normal to lamellae aligned perpendicular to shearing surfaces) and {open_quotes}transverse{close_quotes} lamellae (normal to lamellae aligned parallel to shearing direction) according to small-angle X-ray scattering, SAXS. The present study has determined how these two populations of lamellae are arranged and how they relax upon quiescent annealing by examining the superstructure via FE-SEM.
