• 3D imaging
• Ternay polymer blend
• Phase-separation structure

Two novel phase-separation morphology are reported in the ternary polymer blends of poly(propylene)/nylon-12/poly(lactic acid) by utilizing a high-contrast X-ray computerized tomography. One is a %26quot;mosaictiling%26quot; structure, where each of three components forms equally-sized droplets in a three-dimensional tessellation manner. The other morphology is a %26quot;worm-like%26quot; structure. Two components of the three form successive droplets like stripe socks. These results strongly suggest the wide variety of the phase-separation morphologies in ternary polymer blends.
