| 摘 要： | 利用双螺杆挤出机制备了聚苯硫醚(PPS)/多壁碳纳米管(MWCNTs)复合材料,然后通过差示扫描量热法(DSC)研究了纯PPS以及PPS/MWCNTs复合材料的等温结晶过程,并运用Avrami模型对纯PPS以及PPS/MWCNTs复合材料的等温结晶动力学进行分析。研究结果表明,MWCNTs的加入明显缩短了PPS的半结晶期,提高了结晶速率;Avrami模型能够较好地描述PPS及PPS/MWCNTs复合材料的等温结晶动力学。

| Abstract: | The PPS/MWCNTs composite was prepared by twin-screw extruder.The isothermal crystallization progress of pure PPS and PPS/MWCNTs composite were characterized by differential scanning calorimeter(DSC),moreover,isothermal crystallization kinetics of composites were analyzed through the Avrami model.The experiment indicated that the half-crystallization time of PPS got obviously shorten and its crystallization rate raised with the addition of MWCNTs,Avrami model could well described isothermal crystallization k... |
