镁石-TOA是一种与四辛基铵阳离子和质子共交换的蒙脱石粘土。以氧化镁为引发剂，在80℃进行了己内酯-己内酯(CL)的本体聚合，制得了不同质量分数的氧化镁/蒙脱土纳米复合材料。用X-射线衍射仪研究了原生镁砂与四辛基铵阳离子和质子阳离子交换前后粘土分层的变化。用X射线衍射仪、透射电子显微镜、力原子显微镜和热重分析仪对所制备的纳米复合材料进行了表征。并对其力学性能的演变进行了研究。
Maghnite-TOA is a montmorillonite clay co-exchanged with tetraoctylammonium cations and protons. Bulk polymerisations of epsilon-caprolactone (CL) induced by Maghnite-TOA were conducted at 80 degrees C and produced poly(epsilon-caprolactone)/Montmorillonite nanocomposites with different wt% of Maghnite. X-ray diffraction was used to investigate the changes in clay stratification before and after cationic exchange of raw Maghnite with tetraoctylammonium cations and protons. Resulted nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), force atomic microscopy (AFM) and thermogravimetry. The evolution of mechanical properties was also studied.
