Abstract

The quantitative three-dimensional (3D) observation of phase separated structures of a polystyrene (PS)/poly(methyl methacrylate) (PMMA) blend without treatment for contrast enhancement by x-ray phase tomography was investigated. A clear contrast between PS- and PMMA-rich phases at a spatial resolution of 10 μm was observed. The contrast resolution, in terms of density resolution, is found to be 3.6 mg/cm³. Results show that the image quality attained by X-ray phase tomography is excellent for the three-dimensional evaluation of polymer blends.
