Abstract

We performed a quantitative three-dimensional observation of polystyrene (PS)/poly(methyl methacrylate) (PMMA) blends by X-ray phase tomography mainly using the crystal X-ray interferometer at the beamline 20XU of SPring-8, Japan. We observed the time change in the phase-separated structures of PS/PMMA blends annealed at 180°C. We also measured the densities of PS- and PMMA-rich regions in a series of PS/PMMA blends annealed in the temperature range from 220 to 300°C and determined part of the phase diagram of these blends. Finally, we performed a preliminary trial of X-ray phase tomography using an X-ray Talbot interferometer, which will facilitate better control of the environment around a sample than that possible with a crystal X-ray interferometer.
