X-ray Scattering Patterns of Two Styrene-diene-styrene Triblock Copolymers

Images courtesy Sasha MyersTwo-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).
