采用熔融共混挤出法制备了聚苯硫醚(PPS)/玻璃微珠 (GB)复合材料,考察了PPS/GB复合材料的相容性、结晶形态,并采用Ozawa方程和R-t关系法研究了复合材料的非等温结晶动力学.结果表明,PPS/GB复合材料在熔融状态下两相之间有良好的相容性,而在固态条件下随着GB含量增加存在分散不均匀现象.复合体系中PPS主要生成球晶,GB在PPS基体中起异相成核作用,加速其结晶.Ozawa方程和R-t关系法能较好地描述复合材料的非等温结晶动力学.

PPS/GB blends are prepared by extrusion compounding PPS with different mass fraction of surface treatmented GB, and the compatibility, crystalline morphology and non-isothermal crystallization kinetics of the blends are introdued. The results show that the compatibility of PPS/GB melting blends is favorable, while the blends appear uneven distribution under solid state. GB as heterogeneous nucleation did not affect the spherulite morphology of PPS. Ozawa equation and the relation of R-t can characterize the non-isothermal crystallization behavior of PPS and its composites.
