Abstract：
The addition of two-dimensional inorganic nanomaterials can effectively enhance the properties of polyethylene (PE). In the present study, a series of high-performance PE/oleic acid (OA)-siloxene nanocomposites were prepared by in situ polymerization using OA-siloxene-supported Ziegler-Natta catalysts. Compared with the conventional Ziegler-Natta catalyst, the polymerization activity of the OA-siloxene-supported Ziegler-Natta catalyst was enhanced to 100 kg/mol-Ti•h, an increase of 56%. The OA-siloxene fillers exhibited excellent dispersion within the PE matrix through the in situ polymerization technique. Compared to pure PE, PE/OA-siloxene nanocomposites containing 1.13 wt% content of OA-siloxene showed 68.3 °C, 126%, 37%, and 46% enhancements in Tdmax, breaking strength, modulus, and elongation at break, respectively.
摘要：
二维无机纳米材料的加入可以有效增强聚乙烯(PE)的性能。在本研究中,利用OA-硅氧烷负载的Ziegler-Natta催化剂通过原位聚合制备了一系列高性能PE/油酸（OA）-硅氧烷纳米复合材料。与传统的齐格勒-纳塔催化剂相比,OA-硅氧烷负载的齐格勒-纳塔催化剂的聚合活性提高到100kg/mol-Ti·h，增加了56%。OA-硅氧烷填料通过原位聚合技术在PE基质中表现出优异的分散性。与纯PE相比，含有1.13wt%OA-硅氧烷的PE/OA-硅氧烷纳米复合材料显示68.3°C，126%,37%,Tdmax增强了46%，断裂强度,模数,和断裂伸长率，分别。
