| 中文摘要 | nanostructure and morphology and their development of poly(di-n-hexylsilane) (pdhs) and poly(di-n-butylsilane) (pdbs) during the crystal-mesophase transition are investigated using small angle x-ray scattering (saxs), wide angle x-ray diffraction and hot-stage atomic force microscopy. at room temperature, pdhs consists of stacks of lamellae separated by mesophase layers, which can be well accounted using an ideal two-phase model. during the crystal-mesophase transition, obvious morphological changes are observed due to the marked changes in main chain conformation and intermolecular distances between crystalline phase and mesophase. in contrast to pdhs, the lamellae in pdbs barely show anisotropy in dimensions at room temperature. the nonperiodic structure and rather small electronic density fluctuation in pdbs lead to the much weak saxs. the nonperiodic structure is preserved during the crystal-mesophase transition because of the similarity of main chain conformation and intermolecular distances between crystalline phase and mesophase. |
