| 摘 要： | 利用快速增压和淬火2种方法分别制备了非晶聚醚醚酮(PEEK), 并利用二维广角X射线衍射(WAXD)研究了2种非晶样品在不同拉伸温度(Td)和不同应变速率(v)条件下的结晶行为. 结果表明, 在相同拉伸温度及应变速率条件下, 快压样品的临界结晶应变明显低于淬火样品; 随着拉伸温度和应变速率的升高, 2种样品的临界结晶应变均逐渐降低; 在相同应变条件下, 拉伸温度对PEEK材料结晶度的影响很大, 而应变速率对其影响较小.

| Abstract: | The crystallization behavior of poly(ether-ether-ketone)(PEEK) prepared by rapid compression(RC) and quenched cold(QC) drawn at different drawing temperatures(Td) and drawing speeds(v) were studied by wide angl X-ray diffraction(WAXD). The results show that the critical crystallization strains of RC samples are lower than that of QC samples under the same drawing conditions and reduced with drawing temperature and speed increasing. The crystallinity of samples drawn under the same temperature changed unconspicuously with the drawing speed increasing. Moreover, as drawing temperature increased, the crystallinity is improved obviously. The results show that crystallinity depends on drawing temperature mainly. |
