熔融复合是制备热塑性纳米复合材料最常用的方法之一。本研究的目的是评估加工设置和条件对低密度聚乙烯/有机改性层状硅酸盐（OMLS）纳米复合材料的结构和性能的影响，该复合材料通过浓缩母料路线的两步法获得。浓缩母料的配方和稀释进行了研究，通过形态学和物理表征与最终的纳米复合材料结构的加工参数相关。即使关于浓缩母料发生良好的分散/插层，在母料稀释过程期间进一步OMLS分散的可能性也显著地取决于挤出机混合能力，这对母料技术在净成形过程中的工业应用具有重要影响。Polym.工程索引，2013.© 2012年塑料工程师协会
Melt compounding is one of the most used methods to produce thermoplastic-based nanocomposites. The aim of this study is the assessment of the effects of processing set-up and conditions on the structure and properties of low-density polyethylene/organically modifies layered silicate (OMLS) nanocomposites obtained by a two-step process by concentrate masterbatch route. Concentrate masterbatch formulation and dilution have been investigated to correlate processing parameters with final nanocomposites structure by means of morphological and physical characterization. Even if a good dispersion/intercalation occurred regarding concentrate masterbatch, the probability of a further OMLS dispersion during the masterbatch dilution process depends remarkably on the extruder mixing capacity, with important consequences for the industrial application of masterbatch technology in net shape forming processes.
