摘要
制备了聚丙烯(PP)/改性海泡石复合材料,采用SEM、XRD、DSC、TG等测试方法对该复合材料的结构和性能进行了研究。结果表明:改性处理的海泡石在PP基材中分散均匀;少量改性海泡石的引入增大了PP的结晶度以及微晶尺寸,并且提高了PP材料的热稳定性和力学性能。
Polypropylene（PP）/modified sepiolite composites was prepared,and the structure and properties of the composite were studied by means of scanning electron microscopy（SEM）,X-ray diffraction（XRD）,differential scanning calorimetry（DSC）,and thermogravimetric（TG） analysis.The results show that the modified sepiolite disperses evenly in PP;the crystallization degree and crystallite size of PP increases with the small amount of modified sepiolite,and also the thermal stability and mechanical properties of PP improve.
