摘要(Abstract)：

通过熔融共混法制备了聚苯硫醚(PPS)/石墨烯(G)复合材料,采用扫描电子显微镜、差示扫描量热仪研究了PPS/G复合材料的断面形貌及非等温结晶过程,利用莫志深方程、Dobreva方程和Kissinger方程分析了非等温结晶动力学行为。结果表明:石墨烯质量分数低于0.5%时,其在PPS基体中具有较好的分散性;石墨烯起到了异相成核作用,使PPS/G程、Dobreva方程和Kissinger方程则进一步验证了石墨烯的引入促进了PPS/G复合材料的结晶。
Polyphenylene sulfide(PPS)/graphene(G) composites were prepared by melt blending. The crosssection of PPS/G composites was studied by scanning electron microscopy, and the non-isothermal crystallization process of PPS/G composites was studied by differential scanning calorimeter. The non-isothermal crystallization kinetics were analyzed by the Mohsen equation, the Dobreva equation and the Kissinger equation. The results show that when the graphene content is less than 0.5%, it has better dispersibility in the PPS matrix. Graphene plays a heterogeneous nucleation, which increases the crystallization temperature and accelerates the crystallization rate of the PPS/G composite. The Mohsen equation, Dobreva equation and Kissinger equation further verify that the introduction of graphene promotes the crystallization of PPS/G composites.
