The mechanical properties of system of HPVC/MMT composites showed, the notched impact strength of HPVC/MMTOme nanocomposite was 1.08 times of that of pure HPVC, but the notched impact strength of PVC/Na-MMT composite increased only 29%.

• 但是，硬质PVC/Na一MMT复合体系的缺口冲击强度只提高了29%25，蒙脱土层间距还是1.；29nm，属于普通填充型复合材料。
