X-ray phase tomography, which measures X-ray phase shift caused by a sample with X-ray interferometry in plural projection direction, was applied for three-dimensional observation of the phase separation structures in polymer blends without treatments for contrast enhancement. A demonstration was performed for polystyrene/poly(methyl methacrylate) blends using synchrotron radiation and a crystal X-ray interferometer. Bicontinuous structures were clearly revealed in phase tomograms with a spatial resolution of 10 microns.
