在这项研究中，室温离子液体（RTILs）的基础上的鏻阳离子已被用作有效的增容剂的聚烯烃/聚酰胺6/合成滑石粉共混物使用熔融挤出工艺。因此，在聚合物混合物中以各种浓度（1、5和10重量%）引入由各种抗衡阴离子（次膦酸盐对双三氟甲磺酰亚胺）官能化的不同离子液体。研究了共混物的结晶行为、热性能、力学性能及形态结构。透射电子显微镜（TEM）的显微照片表明，使用一个非常低的量的离子液体（1重量%）导致分散的PA 6相的尺寸显着减少。此外，PP/PA 6/滑石粉的热性能显著增强（+80 °C），并且机械性能得到改善，而不降低断裂应变，表明纳米滑石粉和离子液体之间的协同效应。
In this study, room temperature ionic liquids (RTILs) based on phosphonium cations have been used as effective compatibilizers of polyolefin/polyamide 6/synthetic talc blends using a melt extrusion process. Thus, different ionic liquids functionalized by various counteranions (phosphinate versus bistriflimide) were introduced at various concentrations (1, 5 and 10 wt%) in the polymer mixtures. Then, the crystallization behaviour, the thermal and mechanical properties of blends as well as the morphologies were investigated. The transmission electronic microscopy (TEM) micrographs demonstrated that the use of a very low amount of ILs (1 wt%) led to a significant reduction of the size of the dispersed PA 6 phase. Moreover, the thermal properties of PP/PA6/talc were dramatically enhanced (+80 °C) and the mechanical performance was improved without reducing the strain at break suggesting a synergistic effect between nanotalc and ionic liquids.
