将改性的纳米蒙脱土(MMT)和官能化的多壁碳纳米管(MWCNTs)进行复合,然后负载 TiCl4催化组分,制备出纳米载体 Ziegler-Natta 催化剂,最后进行乙烯原位聚合得到含有多维纳米材料的聚乙烯基复合材料。通过调控纳米载体中两种材料的组成,研究蒙脱土/碳纳米管组成对纳米复合材料性能的影响。结果表明:纳米蒙脱土、改性碳纳米管复合作为催化剂的载体,能够得到高活性的乙烯聚合催化剂。两种纳米材料组成的改变,会影响聚乙烯复合材料的力学性能。当多壁碳纳米管与蒙脱土比例为1∶1时,所得到的复合材料的拉伸强度为38.7MPa。

Several heterogeneous Ziegler-Natta catalysts were prepared by loading TiCl4 using mixture of modified montmorillonite (MMT)and functionalized muti-walled carbon nanotubes (MWCNTs)as effective composite nanofillers.The polyethylene nanocomposites were produced by in-situ polymeri-zation with these catalysts.The effect of composition of MMT and MWCNTs on the mechanical prop-erties of polyethylene nanocomposite was investigated.The results show that highly active polymeri-zation catalyst with the nanofillers containing MMT and modified MWCNTs can be obtained.The composition of nanofiller has a remarkable influence on mechanical properties of polyethylene nano-composite.The maximum tensile strength of polyethylene nanocomposite is 38.7MPa using the mass ratio of MMT to MWCNTs of 1∶1.
