摘　　要：通过悬浮聚合法成功制备了聚苯乙烯小球(PS),但由于聚苯乙烯小球的表面没有功能性基团,很难与其他材料复合,使用浓硫酸对其进行磺化改性,通过控制磺化时间得到合适的SPS小球。通过SEM、红外、XRD表征发现,当磺化时间为2 h时,得到的SPS小球形貌最佳。In this paper,polystyrene spheres(PS)were first successfully prepared by suspension polymerization.However,as there is no functional group on the surface of the polystyrene spheres,it is difficult to combine with other materials.In this paper,concentrated sulfuric acid was used to sulfonate the spheres,and appropriate SPS spheres were obtained by controlling the sulfonation time.The SEM,IR and XRD characterizations showed that the SPS beads had the best morphology when the sulfonation time was 2 h.
