中文摘要:
      选用十六烷基三苯基溴化磷对麦羟硅钠石进行有机化插层改性,制备出有机麦羟硅钠石,并将其与聚丙烯(PP)通过熔融插层制备聚丙烯/有机麦羟硅钠石纳米复合材料。通过X射线衍射、扫描电镜和透射电镜测试表明此纳米复合材料为插层型与剥离型并存的结构。利用差示扫描量热分析法研究了纳米复合材料的熔融与结晶过程,结果显示纯麦羟硅钠石与有机麦羟硅钠石的加入对PP的熔点影响不大,但明显提高了聚丙烯的结晶温度和结晶度。力学性能测试表明,有机麦羟硅钠石对聚丙烯的拉伸和冲击强度提高效果明显优于纯麦羟硅钠石。
英文摘要:
      The organic magadiite (Org-Maga) was prepared by the hexadecyl triphenylphosphonium bromide intercalating into the magadiite (Maga) through ion-exchange method. And the polypropylene (PP)/Maga(Org-Maga) nanocomposites were prepared through melt intercalation method. The X-ray diffraction (XRD), scanning electron microscope (SEM) were used to investigate the structure of Org-Maga and PP/Org-Maga nanocomposites, both the intercalated and exfoliated structure could be found in the PP/Org-Maga nanocomposites. The tests of differential scanning calorimetry (DSC) indicate that the addition of magadiite could significantly raise the crystallization temperature and increase the crystallinity of PP, but hardly change the melting point. The effect of the Org-Maga in PP is superior to the pure Maga on the tensile strength and the impact strength of nanocomposites.
