| 英文摘要 | The morphological structure of poly (trimethylene terephthalate) (PTT) thin films solution-cast at various temperatures was investigated by using polarized light microscopy and atomic force microscopy techniques. Different morphologies of the PTT films were observed at different crystallization temperatures (T-c). In the temperature range of 363-403 K, banded spherulites occurred. When T-c=413 K, the center location of the spherulite showed banded structure, while the outer region of the spherulite displayed a spherulite structure without ring-band. When T(c)greater than or equal to423 K, the normal non-banded spherulite was found. The main reason for producing the ring-banded spherulite is the effect of residual solvent during the crystallization processs of the solution-cast films. At higher crystallization temperatures (greater than or equal to423 K), no residual solvent exists during the crystallization of the films since the evaporation rate is higher at higher temperatures. So no banded structure is formed. |
