Two-dimensional small-angle x-ray scattering patterns reveal the nanostructure of two styrene-diene-styrene triblock copolymers which have been aligned through channel die compression. Left: a lamella-forming triblock showing a biaxial texture (four-spot pattern). Right: a cylinder-forming triblock showing a single-crystal texture (six-spot pattern).
