| 中文摘要 | syndiotactic polystyrene (sps) nanorods of 200 and 80 nm diameters were prepared by infiltrating porous anodic alumina oxide templates with polymer melt, and the crystallinity and orientation of various forms of sps crystals in the nanorods were studied by ftir spectroscopy and electron diffraction. for sps crystallized from amorphous state at lower temperatures, a-form crystals were found in the nanorods with random orientation and the same degree of crystallinity as that in the bulk. however, for sps crystallized from molten state at 260 degrees c, while no preferred orientation was found for the chains in the melt, the beta-crystals formed in the nanorods oriented preferentially with the c-axis aligning perpendicular to the axial direction of the nanorod, and the degree of crystallinity was significantly lower than that in the bulk. the crystallinity decrease was more profound for nanorods of smaller diameter. these results were also supported by electron diffraction data and can be attributed to competition between nucleation and crystal growth in the nanotemplates. |
