A facile coagglomeration method for preparing a long alkyl chain modified graphene oxide (MGO)/MgCl2-supported Ti-based Ziegler-Natta catalyst was reported. The effects of MGO on the catalyst morphology and activity for ethylene polymerization were examined. The resultant polyethylene (PE)/MGO nanocomposites exhibited a layered morphology, with the MGO fillers being well dispersed and exhibiting strong interfacial adhesion to the PE matrix. The thermal stability and mechanical properties of the PE were significantly enhanced with the introduction of a small amount of the MGO filler. Thus, this work provides a facile approach to the production of high-performance PE.
报道了一种用于制备长烷基链改性氧化石墨烯（MGO）/MgCl₂负载钛系齐格勒-纳塔催化剂的简便共凝聚方法。研究了MGO对催化剂形态及乙烯聚合活性的影响。所得聚乙烯（PE）/MGO纳米复合材料呈现层状形态，MGO填料分散良好，并与PE基体表现出强界面粘附力。通过引入少量MGO填料，PE的热稳定性和力学性能得到显著增强。因此，这项工作为高性能PE的生产提供了一种简便方法。
