| 高分子材料の高次構造形成過程の追跡 In-situ Observation of Structure Formation in Polymer Processing |
村瀬 浩貴 Hiroki MURASE |
| ＜要旨＞In-situ X-ray scattering in polymer processing is a crucial method to elucidate
the mechanism of structure formation in the process. Fiber spinning is
one such process primarily imposing extensional deformation on polymeric
melt at the spinline during rapid cooling. In-situ small-angle X-ray scattering
using synchrotron radiation on the spinning process allows direct observation
of the transient structure developing in the process. Keywords: Synchrotron Radiation / Small-Angle X-ray Scattering / Fiber Spinning / Crystallization |

of filler in rubber was performed by imaging X-ray tomography coupled with
phase-contrast techniques. Keywords: Refraction-Contrast imaging / Imaging CT / Phase Contrast CT / Rubber / Soft Material |
