Morphology diagram for blended polymer system (IMAGE)
Caption
The morphology diagram derived from the x-ray scattering data shows where in the composition space the cylinders, lamellae (vertical sheets), spheres, and disorder occur. Pure PS-PMMA block copolymer is located at the top of the triangle, and pure PMMA and PS homopolymers are at the lower left and right of the triangle, respectively. Each colored point represents a single x-ray measurement (the numbered points correspond to measurements described in detail in the paper).
